Variant: Cannot Apply "Change to" selected variant when prototyping


I wanted to change the dropdown menu status from my prototype, and I’ve made it with variants.

However, when I apply an interaction of “click” and setting it “change it” to change the status of the dropdown menu, the other variant option that I made is enable and can be selected, BUT CANNOT APPLY THE SETTINGS. (As below pic)

If this option is not available due to ANY of my settings conflicted somehow, please disable the option for troubleshooting. Thanks!
