Why can't I see Padshop Pro's Patch selector in N 5.5.4?

I don’t get this: it seems that in the previous version of Nuendo I could see PadshopPro’s native file selector (the one at the bottom-center of the GUI), and I see it in my other hosts, but now I don’t see it in Nuendo 5.5.4. The Media Bay only shows me the native and Zero-G banks. I don’t see the Patchpool bank I could see before. And I do see all three sample banks from the sample file selector which still works.

How do I get the file selector to appear again?
