The problem is in the quick controls section of 7.5
Not at my music rig, but I had the same problem.
Disable the quick controls & you’ll be fine

Edit - looked up one of my previous replies:
I had a similar problem with my Kenton Control Freak & Korg NanoKontrol.
Had me scratching my head until someone sorted it out.
I thought it was a problem with Nexus, which has hard wired midi cc’s.
But it isn’t
In 7.5, as well as Track Quick Controls, there is also VST Quick Controls.
These use 71, 73-77, 97 & 98.
That is the probable problem.
Oh & check 16-19, 79-82 as well for the track quick controls.
Hope that helps
