I'm seeing the builds for other specs in a diff spec (ex. outlaw builds showing up in the dropdown when I'm in sub). This happens with no errors popping up.

It only seems to happen with builds that were originally imported to the Blizzard default loadout system. Then, even after they've been deleted, swapping to a diff spec will have the ImprovedTalentsLoadout dropdown showing copies of those loadouts from that other spec.

Here is an example:

In this picture, I am currently sub. The dropdown is showing builds from outlaw and assassin.

Could you send me your SavedVariables file if it still happens? Sorry for the late response, i was busy studying.
