MuseSounds brass MIDI files not working properly

For some reason, when I updated MuseScore for the first time in a few months all of a sudden none of the brass parts on any of my scores using Muse Brass have any audio playback. The percussion and woodwind Muse Sounds do not seem to have this issue for me.

CORRECTION***
This issue is not present on all of my scores. Just mainly one that I have put significant amounts of hours into writing.
Final correction, I closed the application and reopened it a second time and the issue was resolved.
