I get an email called weekly summary. It contains a link to 20 unresponsive agents.

When I click on it it goes to ../account/agents?filters%5Bunresponsive%5D=1

Which actually shows a list of all the agents.

When I turn on the unresponsive filter from that page the url changes to

../account/agents?search=&agents_grid%5Bagent_status%5D%5B%5D=unresponsive&load_grid=true

and filters correctly.
