Incomplete and missing metadata being imported to Library

Hi,
Let me start by saying that I am really excited to see that a Mac version of MM is now available, so as soon as I found out earlier today I downloaded it straight away, bought a Lifetime Gold license and imported my music library of 5,067 MP3 and FLAC files. I have found an initial bug that is detailed below and will report any other things that I find when I come across them.
This is a strange one, as the metadata for various fields is either not being added, is the wrong value or is being truncated to 30 characters. Only 214 of the 5,067 files in my library have been imported correctly with nothing missing. The fields that are affected on the ones imported incorrectly are...
Empty fields with no values in them = Disc #, Conductor, Genre, Lyrics, Grouping, Artwork
Album Artist - when it's populated, it contains the same value as the 'Artist' field rather than the 'Album Artist' value (which is always different in my case), but some records are blank and the ones over 30 characters have been truncated.
I have tried to add screenshots to this post using the instructions in the 'Forum rules / Using the forum / Attaching screenshots' post, but I keep getting the error message "You don’t have rights to post image, email or url links that are external to this domain" when submitting despite inserting a space into the URL as suggested. I can email screenshots to you though if you need to see them.
I have imported my library into iTunes to make sure that the files do actually contain the metadata and they have all been imported successfully with all of the blank values detailed above showing correctly, so there is no issue with the MP3/FLAC files themselves.
Let me know if you need any more info.
Thanks
Matt
