Can't set recent Fmod Event variable in Blueprint details panel?

For some reason I can’t set certain Fmod events as variables in UE5. ‘Older’ events (ones I made months or weeks ago) are settable, but newer events (created / renamed in the last couple days) won’t set. This happens even with a new totally default blank event.

What I mean by won’t set is that if I create a FMODEvent variable in a BP, I cannot set it’s value in the details panel. When I select the desired event, it just reverts back to none. However, I CAN set it with a Set node for the variable.

Resolved, but I’m not sure why. Either fixing redirectors in UE and/or closing and reopening the project.
