Question: Previously hidden purchased songs reappear in iTunes
I have previously hidden a number of tunes purchased in iTunes Store. Not downloaded. On one machine I have, they now appear in iTunes, as from the cloud. When I try to delete/hide them again, they pop out for a sec, then pop back in, w/ the check box checked for the songs. How to get em out? I tried downloading one of these files, then deleting/hiding again. Still shows in iTunes. This on a Mac Pro 1,1 running 10.9.5. This does not happen on another Mac Pro 3,1 I have, running 10.11.6. Is this an anomaly from old iTunes? Any way to fix? Cannot copy iTunes Library.itl from 3,1 machine to 1,1 machine, newer itl file is not compatible on older machine. Since the songs were never dlo'd (except the test I did, mentioned above which made no difference), I suspect the problem is either the old itl file, or the old version of iTunes app.
Mac Pro 1,1 has iTunes v.220.127.116.11.
Mac Pro 3,1 has iTunes v.18.104.22.168.
Both machines are properly registered under my Apple ID.
