Cannot select filter in gadget

Steps to reproduce:
1. Create new filter with name: AA_1.6_Unresolved
2. In existing dashboard, pick a gadget and try to change the filter to AA_1.6_Unresolved
3. typing in AA_1.6 yields nothing. Nor does 1.6_Unresolved. In fact, no matter what combination you try, you won't be able to select AA_1.6_Unresolved from the drop down menu.

Customer Feedback:

Please reinstate the ability to select the filter in dashboard gadgets via a pop-up window! Recent updates made it impossible for me to select new filters, so I'm totally stuck right now!

There are two issues in play:

1. Multiple filters that contain the name Unresolved doesn't show all available filters in autocomplete.
2. If a filter contains a dash followed by a number it won't be available in autocomplete. For example, the following filter name will cause an issue:

   Filter-6

   but

   Filter - 6

   and/or

   Filter-Six

   are perfectly fine.

Ideally we can manually escape the characters as a workaround until this is fully resolved.
