After matching a couple of albums, I'd like to add some info to the 'comment:' field.
So I:
-select all matched albums
-use the 'add new tag' in the bottom pane
-type in 'comment:'
-insert my info in the value field
-close the dialog by clicking the save button
-apply all changes by saving

If I then go and check the saved files, apparently the inserted info isn't always saved to the 'comment:' field.
For some reason it chooses to save in the correct field or in the 'catalognumber' field seemingly at random.

In the attached image you can see a possible cause of this bug.
I'm typing 'comment:' and it effectively suggests that keyword, but the values shown are those from 'catalognumber' which is the first suggested keyword when starting to type 'c...'
