Grace note duration

I entered an accaciatura to a sixteenth note on a MuseSounds snare drum part where the quarter is 25 bpm as in the image below, expecting to hear a flam. However, the grace note played back on the beat, with the length of a full 32nd note. I understand in faster tempi, the difference is negligible, but at this tempo, it really doesn't sound right. Is there a way to change the duration and/or playback placement of grace notes in MuseScore 4.1?
