My sandbox org with Skuid version 7.20.

When I try to add a filter critera to a lookup, the options to input the filter definition is not showing up.

New lookup filters (Screenshot below)

Existing lookup filters (Screenshot below)

I’ve tried this on existing Skuid pages, on new Skuid pages. Also I’ve tried this on Chrome and Safari (clearing cache etc), and also tried accessing the same org from a colleague’s computer to the same org, and he gets the same behaviour.

On another org (with Skuid 7.20), this feature is working.

Any help would be great. Happy to grant someone at Skuid login access.
