Huge issue

This is what concerns me "Copy of 0003-15.kma"!! Is there another file in the same folder that is just named "0003-15.kma"?? If so there is your duplicate.
If not and this is the only copy in the folder then it isn't actually a duplicate. Back when all the problems were going on with the disappearing song files in versions 3.318 and 3.319 I think this problem was occuring too but was overlooked. Whatever they changed to fix the missing files also fixed this to keep it from occuring again. However if it had already happened their fix did not fix the files themselves.
So if you do not have 2 copies of the KMA file(s) in the folder as I asked in first paragraph, then you need to re-import those files to correct the header so it is no longer recognized as a duplicate the next time you rebuild.
