Crescendos, decrescendos and forte pianos do not work with percussion tremolos (playback) (rolls)

In any scores I make, if I put a tremolo on a percussion note to do a roll and then put a crescendo/decrescendo/forte piano on it, the playback won't do the inserted dynamic.

For the crescendos/decrescendos, it will only change the playback dynamic when arriving on the last note.
For forte pianos, it will only take the forte into consideration.
