Season's greetings to everyone. 😃
There appears to be a bug in the Master Equalizer section after doing a Full Restore.
Try this:
- Create a normal (with correct EQ settings) full backup
- Mess up your master eq section
- Restore your full backup
Now when you look at the Master EQ, it all LOOKS correct, but it plays per your messed up settings. If you close the app and reopen it, it takes on the restored settings correctly.
