Hello. I'm fairly new to mp3tag and would greatly appreciate some assistance.
I added the Subtitle column, but for some reason, the panel on the left side of the screen and the list in the middle of the screen do not sync.
Tag Panel (on the left) and file list in the middle are independent from each other. You have to customize each separately.
If you have problem with a column definition, please show that as well in addition to the field definition for the tag panel.
See also the documentation on the customization.
