Rehearsal Marks, frame is missing

I’ve just added a rehearsal mark to one of my arrangements. In contrary to earlier pieces de contour (square) of the rehearsal mark seems to be gone.
Where can I adjust the look of rehearsal marks?

Engraving Options generally contains settings for the look, design, or style of notation.

There’s a category for Rehearsal Marks.

Thanks Ben,
That helped. I’m still trying to find my way in Dorico (Old Finale user). Live and learn.
