[Finale 25.5 on Windows 10]

I'm having a devil of a time understanding why the playback volumes/velocities are completely "upside down" from what they should be. In other words ppp is blaringly loud and fff is ultra quiet, and everything in between is equally the opposite of what it should be.
I'm trying to apply a Jazz-style HP to get the swing feel, but when I do, the playback volumes are completely wrong.

I've also tried setting HP to "None" and using the MIDI tool to apply HP to specific ranges of measures, but it seems to completely ignore this, so that feature doesn't seem to be working either. How can this product, which is so mature, be so messed up like this? I would expect bugs in an early version, but what's going on such that I'm having issues like this in v25.5?

I've attached the .musx file, in case anyone can diagnose it or fix it. Ideally ms 1-7 would be straight, ms. 9-42 would have a jazz swing, ms. 43-50 straight again, and 51-end would swing. But I can't seem to get this HP to apply selectively to these measures. And if I turn Jazz HP for the whole score, it all swings, and the dynamics are all wrong!
