Context Views in Smart Folders broken?

Hi there,

I can use and create Views as normal everywhere else, and I’m an Admin, but for some reason I can’t create Context Views in Smart Folders anymore. This is what I see when I hover over an entity in a Smart Folder (in Architect Mode)

But I think it should look like this:

(from the article on Context Views)

Context Views that I already created are still there, though.*

Thanks!
