Issues with Selecting List Properties in Lookup Tables

Hi everyone, anyone else having issues with list properties in Lookup tables? I’ve just noticed that I can no longer select any of the properties that are of List type in any report building features. When I select one it briefly shows a little blank panel at the bottom of the overlay window but never actually selects the property for the filter or breakdown. Any reports I had already created are working fine but if I try to update the breakdown or filter property or even select the same one that is already selected it doesn’t work. Any help appreciated, I’ve raised a support ticket last week but haven’t heard anything back yet. Thanks for your help.
