Queue Filters Do Not Display

Hi there - 

The gear icon on my queue stopped working. It should be showing filters, but clicking on it now just shows a horizontal line underneath the queue title. 

There has been some other strange queue behavior (for a while I could get the filters to show up while i was troubleshooting the page include not working, but they rendered on top of the queue items, for example.)

I’ve just updated to the latest version of Brooklyn. I deleted the queue component and built it again and still - not working.
