Pro Sites plugin will not allow Premium Themes to be activated for micro sites

Hello!

Since the last update to the pro sites plugin the "premium themes" function does not work. Please help me troubleshoot what is wrong.

I've enabled "premium themes" under "Modules".

Next, under "Premium themes" I've selected the minimum level at which that theme should be used.

I'll go to that micro site in which I want to use the theme and it does not appear.

Please help! We are doing a massive update and this is critical.

Thank you!!
