<<< These issues should, IMO, be fixed. >>>

I certainly agree to that. My concern is that I may not be correctly understanding your workflow or your intended end result of your project song and I may be giving you advice to help solve a problem you don't have.

Will you be using the imported audio file to be included in the final version of your song?

If not, are you deleting the audio file after you have used it to construct your song structure, tempo map, and chord analysis and your final version is a BIAB generated sound track?

If you are using the audio file in your project, I'm not understanding why you are copying and pasting chord sections after you have analyzed the chords to correctly follow the audio.
