Problem adding suffixes on template features

Hello,
After the upgrade to Joomla 3.7 and University template 3.22 I can't add suffixes for pages in Template Features. I have reinstalled the template but the problem continues.
As soon as "Add Rule" is clicked, nothing happens. Have tried it with different browsers, but still the same.
Any information how to fix it?

Thanks

HI, I have the same problem with Steak House template...

Same problem, I can't add any Suffixes...

Hi

That's been reported to programmers already. Will inform You when this will be fixed.

Hi

I'm getting an information that packages has been updated with a fix to it, so please update templates to the latest version.

Unfortunatelly with SteakHouse template the problem is still not fixed. I have the version 3.22.

Hi

That's odd. It worked with my copy of this template. Are You sure browser cache was cleared to load changed files ? Try that and if this will not work send me an access to joomla panel to my email [email protected]
