Search tree - not finding w4a files

[NeilVP]

Newbie installer with codec extension pack included. If I manually point to a w4a file it will play. The option to search for w4a files is set but I can't get search function to find the w4a files. In telling MonkeyMedia which folders to search it stops at at the 2nd level down and won't let me get to the sub-folder where the files are. How do I fix this please?
MediaMonkey Gold 4, Windows 10

So the problem is in Add/Rescan Files and the ability to drill down enough sub-folders?
