Filters on left side don't work

Some sidebar links and filters don't work.

For example, for events clicking on admins or going does nothing.
This means that we can't approve pending members for private events.

I have tested this using the standard Joomla Prostar template and everything works fine. They only stop working when we use the latest Office template.

We have seen this so far on Event attendees, Custom search filters and Group member filters, but I'm sure there are lots of other affected areas.
