Drumset dynamics are all funny

For some reason, in this piece the snare hits are really quiet whenever there's a hi-hat at the same time (e.g. bar 6 and 7 beat 4) and side sticks are really loud whenever there's a hi-hat at the same time (e.g. bar 61 beat 3). They sound the same as pre-update when there is no hi-hat at the same time, though.

The bass drum also seems a bit louder, but I suppose that could've been intentional (and I'm fine with that).

The sounds worked fine before the update, and since drumset doesn't have a Muse Sound, I suspect it's a Musescore and not a Muse Hub problem. It's probably not clipping also because no other instruments seem to be similarly affected, and if it were clipping I would expect both side sticks and snare hits to be quieter.
