Capo chords stopped working properly

I have a guitar part using drop d tuning and capo on the 4th fret. I entered the main chords and then turned on capo chords and everything worked fine. I made a separate layout for just the vocal parts. I was trying to figure out a way to show the chords in the vocal parts layout and something I did seems to have caused the capo chords to stop working: they now show up the same as the main chords. Any ideas about how to fix this deeply appreciated!
