Scrolling through user sets in 2.5

I am unable to scroll through user created presets. When I attempt to scroll using the drop-down menu arrow keys it goes to refresh list instead.

Why is there 3 of the same issue under 3 different names? In any event none of you is giving any information of your set up. I just tried tis on my Mac OS Catalina and it seems to work just fine.
What is your OS? Have you tried upgrading to 2,6? Have you tried rebooting? Did this work for you before?
