So I tried Judson’s remedy and got very excited because it made sense…but unfortunately it didn’t change anything. Still the cymbal was getting choked.
I then however found that when I looked to the right of where you select the cymbal/instrument, you can also find which articulations are loaded. For me, both “Crash” and “mute Hit” were loaded. I deactivated “Mute Hit” and voila the cymbal sustained!
