Auto voice leading etc sometimes doesn't appear

I’m having trouble with the Auto Voice Leading, Octave and other options not appearing for some particular but seemingly random chord selections. It’s as if for some reason some particular chord transition gets excluded from these functions. Is this a bug, or is there a logical reason for it?

See the provided example screenshots, showing the following:

When C# sus4 to B sus2 was selected the options for Auto Voice Leading, Octaves etc appeared down to the left.

When B maj to A maj was selected the options also appeared.

When B sus2 to B maj was selected the area with the voice leading etc remained blank.

This behavior occurs quite often, and it stops me from being able to select all chords in the song and do Auto Voice Leading on all of them. Instead I have to do it in smaller chunks until I can locate the offending chord switch that is stopping the options for being shown.

Is there a reason for this behavior, or should I create a bug report?
