Hi @roseph.josen the culprit seems to be the layout option Show rehearsal marks below bottom staff. Deactivating it gives the normal behaviour for the deactivated option Show bar numbers at rehearsal marks.

@dspreadbury It is indeed strange that activating Show rehearsal marks below bottom staff seems to influence/annul the expected non-appearance of bar numbers in the presence of Rehearsals marks, (despite the correct settings for the bar numbers to not show at rehearsal marks ) only for the upper staff (the bottom staff, with both bar numbers and rehearsal marks, acts as expected). Or did I miss something?
A similar problem has already been mentioned here.
