Same here : Selecting a new preset on HX Edit is inconsistent : sometime it switches to the selected preset, sometimes it stays on the former one and i might also happen that it switches on the Stomp, but not in HX edit, resulting in overwriting the selected one with the former when adjusting a parameter. Renaming is also inconsistent : sometimes renaming the right preset, sometimes an adjacent one...
Looking forward to V3.01... (any news on a bug-fixed version ?)
Setup: HX Edit 3.0 on Mac OS Catalina + HX Stomp 3.0
