Using Jira's default/built in Projects Gadget.
Days ago before many changes related to setting up our JIRA projects for the first time, the filter drop down menu (icon) was populated with all items listed under the filter icon: https://confluence.atlassian.com/display/JIRA/Adding+the+Projects+Gadget
Now when clicking on the filter icon, a blank drop down menu comes up. Simply a white box with no content.
I've re-indexed, tried to add and share filters based on the menu items, poked around screens and schemes and permissions and fields, wandered around the help and google.
Ideas?
