This is the case:
I want the first two-note chord to be played fingers 1,2 (left hand) and p,p (right hand) . Unfortunately, this is the only way possible to be written.
Placing “p,p” as “next to notes” (so I have a bracket) make them disappear. When I change fingers so they are different (p,i), they disappear also
Placing “1,2” as “right of note” (to make room) does not fix anything.
All other combinations except the one in the screenshot, give strange results.
PS I have made that possible by placing (for the right hand) a horizontal line (bracket) with a fingering. But, I suppose, that is a workaround
*And a SUGGESTION:. Selecting a finger in Engraving mode would be handy to scroll the properties view to finger settings, and not to the note settings
