Not a bug, if you don't do enough to keep using UC trusts they will disappear after the weekely tally and only return until you do enough to get access to them again.

The easiest way by far to get it done is spamming the earn XP RoE objective on monday night. But if you can't wait that long you can do other eminence and Unity objectives instead.
