Stacattisimo is so quiet on strings, why?

I have a score that proves my point here, that being an incomplete arrangement of Beethoven's Piano Sonata no. 1 in F minor, with just the first movement so far being fully arranged. But I noticed while I was listening to it that I get 3 different gradations of loudness save the accent markings and dynamics. Those being:

1) Default Legato sound - Loudest(at written dynamic level)
2) Staccato - Quieter(if at piano, it sounds pianissimo)
3) Staccatissimo - Quietest(if at piano, it sounds pianississimo)

I don't get this issue with the piano instrument, just the strings. It really ruins the sonata to have staccattissimo notes at fortissimo and have it play back not even at forte just because I arranged it for string quartet.

While yes, there naturally is a creschendo built into the bowing mechanism, that creschendo is quite quick, way quicker than the quickest staccato possible. So Beethoven's staccatissimo ending chords should be very easily played back at fortissimo. But they aren't, they are at mezzo-forte. I know this is a well known issue with the Musescore General HQ soundfont or whatever that's called, which is the new default soundfont for Musescore 3.

And of course the violins are the most affected by this issue, but I am noticing it even in the cello and viola which are less affected than the violins. But this Beethoven sonata score just proves my point that it is a serious issue. Speaking of which, here is the score:
