I tried a new installation of MM5, today. Now it works perfectly for me too. Sorry for the trouble.

Hi,
Same here on 2060 and Win 10 Pro x64.

Works on my Windows 10 Pro system.

Im using Windows 10 Pro (Insider Preview built 14986). I will submit a ticket.

Interesting, it works here. Win7 64.
You may want to submit a ticket, or another if you did while using 2058.

Sorry, but is not working in 2060. You still can not use the negative selectors ("doesn't equal", "doesn't contain" or "doesn't start with"). All of them default to "contains".

gamb2009,
It appears to be working correctly with latest .2060.

I, too, have a collection named jazz. But personally, I find it useful to have a category - Music - that contains everything in my library (I deleted the Type <> Classical Music that is in the default criteria). To that end I created a collection called Other Music with the criteria Genre <> Jazz and Type <> Classical Music. I then have 4 collections/types:

Classical Music
Jazz
Other Music (everything not Jazz or Classical Music)
Music (everything)

Music is especially useful when trying to find a new set of tracks when the genre/type might be missing.

There will be some major issues in collections fixed in next release.

I'll have to delay testing as I am running into a major error problem myself when trying to do so.
I'll have to send a debug in over the next 24 hours.

For anyone else wanting to test above issue:

Default
coll. name - "Music"
Type; is; Music, Classical Music, etc.

What to create/edit
coll. name - "Jazz" (create custom)
Genre; contains; Jazz

coll. name - "Music" (edit default coll. by adding)
Genre; doesn't contain; Jazz

> press "OK"
______________________________________________________
See if it works to exclude "Jazz".
Either way, open "Music" back up to see if Condition changed from doesn't contain to contains

Ok, I understand now. I'll test later.

Sorry if I have not explained myself correctly (probably is my bad English)... or maybe something wrong with my computer.

I have done the following:
a) I have succesfully created a new Cathegory Named Jazz, adding a fliter criteria: "Genre > contains > Jazz". Works great! Now I have three cathegories in my tree: Music, Classical Music and Jazz.
b) Actually, the Jazz cathegory only have tracks that matches the genre Jazz. But the original cathegory Music have both popular tacks AND Jazz tracks, mixing the two.
c) Now, I want to exclude the Jazz tracks in the default collection "Music", in order to have in it ONLY the general popular music (i.e. other genres), excluding Jazz and Classical Tracks.
d) I edit the cathegory "Music", adding a new selection criteria to the existing one: "Genre > doesn't contain > Jazz". Hit OK in the dialog box.
e) It doesn't work. Why? If I open again the dialog box for checking and reediting "Music" cathegory, the newly added criteria is there, but it has changed to "Genre > CONTAIN > Jazz.

Hope you could replicate the problem.

I cannot replicate, for me it works as expected, is this what you have meant? :

My purpose was, once succesfully creted a new group in the tree named Jazz (which works correctly), I wanted to remove the jazz tracks form the original group "Music". So I added a new criteria to the existing "Music" group to filter out the jazz tracks from other kind of popular music, as I have now a new cathegory for it. So, if a add to "Music" in the quantifier all "Genre > doesn't contain > Jazz", and then hit Ok to the dialog box, when I come back to it, I get "Genre > contain > Jazz". i.e. the opposit.

Can you state/confirm what you are doing in the following format, like if I use,

1. Using quantifier "all"
2. Property: genre, Condition: doesn't contain, Value: Jazz
It works to do that one thing.
But you want to add something with "Property: type, Condition: equals, Value: music" to that?
