Custom profile property doesn't return Search results

Hi all, I have a custom user profile property called "TellerNumber." I have crawled and set it up as a managed property (and full crawled again). But when my search query targets the values in this property, I only get results if I explicitly tell Search to target that property:

Works:

Doesn't work:

I have the managed property set to allow searching, refining, querying, the works. Any idea what else I need to do to get the simply query "test1234" to return results just like "TellerNumber:test1234"?
