Respelling Chords

[FossMaNo1]

Hey, folks. I searched through the forum but didn’t find anything on my topic.

My piece is in Bb and I am entering the chord Bb2/A… Dorico keeps changing the symbol to Cbb/A. How do I get Dorico to stop doing this?

Thanks!

Correct popover syntax is Bbsus2/A …

… with this Engraving Option selected:

Thank you!
