I have 50-some instruments loaded in my current working setup, and the menus look normal to me. Could be a problem introduced by loading/unloading, most of my crashes and strange behaviour have come from testing and changing the configuration, not from just starting, loading instruments, and making music. Obvious, probably, but try saving your setup as a .gsp file, exiting, then re-entering and reloading the saved setup.
Also, for your other question, I couldn't see any way to control the quick edit parameters in midi either. I've used midi control for parameters on the effects plugins successfully, but never tried before for the quick edit parameters.
