Leads popup listview doesn't show "My Filters" button

When I click the “Select Delegates” from the Event page, then click the Leads link, the popup listview doesn’t show “My Filters” button.

This link looks somewhat related but says it’s fixed and doesn’t mention the Leads list.

For the record, I did create a filter which shows in the listview, but NOT the popup’s listview, which shows no “My Filters” button at all.

Any suggestions?

That sort of “Select” pop-up never includes Quick filters, to my knowledge… can you find any example in SuiteCRM of a Quick Filter being available in one of those “Select” pop-ups?
