Hey @coffeemaker96 ! I might be wrong but I think what you are describing is what happens when there was previously a c2 cloze that no longer exists because the card was updated. Try tools → empty cards. LMK if that fixes anything.
Agreed, this appears to be most likely a local issue as the card displays find on my end.
Additionally, switching clozes is almost always not the ideal solution as it tends to create new card/s for all users
