Problem Renaming iTunes Tracks

Question

I'd pull my hair out if I had more of it. Periodically, when renaming a track in iTunes the name reverts right before my eyes, when I play the track right after renaming it!
My process:
1. I find the track to rename
2. I select Get Info for the track
3. I select the field "Name"
4. I edit the track name
5. I press "OK"
6. I go to play the song and the old track name reappears instead of the one I just entered!
I've even tried renaming the track in the Finder, so that the edit of the name is now in both the Finder and iTunes, and still iTunes reverts it back to the old name.
Important to Note: This is not a usual occurrence, but happens enough to push me to the edge ...   ;<)

Answer 1

It now sounds like the files have tags.  Some file formats (mentioned before) do not accept tags, and I think some that do may not have tags until they are created.  At least, in my old version of iTunes there is a "create ID3 tags" feature under Advanced and it creates several different versions as well as "none".
iTunes works this way.  You add a file; it reads the tag data (if any) and uses that to fill in entries for that data in its own database (Library.itl), so there's some redundancy here.  If you edit the tag, iTunes changes the information in the database and re-writes the file with the new tag data.  If you use a third party editor to change a tag in a file, it will not change in iTunes until you play or activate reading the file, at which time iTunes compares the file tags to its own database and if they differ it updates its  database to match the file tags.  For some reason when you are now changing a tag in iTunes it seems it is not re-writing the file.  It is changing the data in its own database, but when you play the file it is comparing the datasets, seeing the file has different, and changing it all back again.  I don't know why.  I have seen this happen before and reverted to using a third party editor (MP3Rage) to change the tags on the file.  Tagging protocol isn't cast in stone.  It is possible your dBpoweramp is playing by slightly different tagging rules than iTunes, and iTunes cannot edit the tags in those files but it can still read them.
Things to try:
If the new iTunes still has the create tags feature see if creating the tags will let them be edited.
Use a third party editor.
