Pro Builder can't make stairs

I am using unity 2020.1.16, pro builder is updated from the package manager to 2.9.8f3.
When I try to make stairs I get this nasty list of bugs in the console. I already tried all the repair functions in the Tools->Probuilder->Repair menu. Anyone have any insight? Pro builder used to work fine for me. THank you

The current version of ProBuilder is 4.4, can you try updating?

Did you ever figure this out? I am having the same issue

Ok so I got it. Make sure in package manager you are in “Unity Registry” and not “My assets”

Otherwise if you ever downloaded Pro builder before it was integrated with Unity, you will download 2.9 and not the most recent version. Woops easy mistake.
