It appears the ACW is not doing the analysis of chord detection nor the tempo map. That is why you have no choices when the import window comes up.

The key signature option is also not available if you set the key signature from the main ACW screen.

I noted in looking at the pictures you've provided that the song you've selected is "Frontier" which is a BB demo song and is several years old and could have somehow gotten corrupted. That is one explanation why you get the same occurrence across two computers that resetting to default doesn't fix.

Is your problem with any song imported to the ACW or just "Frontier"?
