Tied Percussion Rolls Sounding as Multiple Rolls

Hi MuseScore!

I have been using MuseScore for a few weeks, and I have noticed that certain percussion rolls sound weird when tied across bars. This includes tam-tam/gong when rolling with a crescendo, where the rolling sound starts rather quietly with little increase in volume, then a sudden crash in the next bar, as if there was no crescendo and no tie. As far as I know, this does not affect other instruments. However, tam-tam/gong, snare drum and suspeded cymbal rolls sound weird when rollinng at the same dynamics, where even when the rolled notes are tied across bars, the rolls sound as if the ties do not exist and the roll audio starts all over again. When I change the tempo to very slow (thus making the note have a longer duration) the audio has no problem, and the roll can last for a long time.

Other than this, MuseSounds has been very impressive and amazing indeed!
Thank you
