I think I understand what you are doing. So essentially you have a one chorus song in BIAB with a MIDI melody track that is longer than one chorus, so there are notes past the last bar of your chorus. Then you are changing the number of choruses and letting BIAB adjust your melody track automatically.

I tested this and it is working as I expect it to - it copies the melody chorus bars "x" times and retains the ending notes. These are the notes that you want in your tag. However it sounds like you want the song to jump from somewhere in the middle of the last chorus to your tag. BIAB isn't going to adjust your melody notes automatically when you set the tag ending, so that's probably what the issue is here. I suppose that you would like it to ask you if you want it to adjust the melody notes when you set the tag, and I suppose that might be possible in theory, but it doesn't work like that currently.

So what you need to do is cut out that portion of the last chorus melody. If you are copying and pasting in a tag ending, the ending bars display 'linearly' in the copy/paste dialog, so you're right about that internally it is thinking of it as the "33rd" bar of the song, even though it has jumped visually to bar "34".
