Role Search Bug: @entitlements(...) Sometimes does not work

Running a search for @entitlements(id:) sometimes works and sometimes does not. I have not been able to determine commonality yet. Using the id of some entitlements from Source1 returns a list of relevant roles and using the id from other entitlements from Soruce1 returns nothing (when I know for a fact they are used in roles). Same thing for entitlements across a number of sources.

Bump on this in the hopes that someone from SailPoint can take a look and assist.
