Add Conditional Column dropdowns not working

[Helpusobi1138]

I am running into an issue with the Add Conditional Column wizard where the dropdown list for the Column name does not work for the if statement, which means that I am unable to add a conditional column. The dropdown list doesn't even drop down, it just does nothing when clicked on. I haven't been able to find this issue anywhere else online, has anybody run into this before? And if so, what is the fix?

Is this in PBIDesktop or Power Query Online? Can you share a screenshot?
