I am on exercise: Create a Wizard from Interface 102: Building A Dynamic Interface from Appian Developer course. I keep encountering this error that I attached. (also included screenshots of my expression to clarify things)

Did you try to follow the description in the error message and check whether that record is synced?
This has nothing to do with the code in your interface.
yes, i even resynced to make sure
Did you resync your Event History record of Maintenance Record as well?
