[Queue] Why are there only "24h" and "immediate" as response times?

I am getting a weird error while using remnote for flash card review. while displaying the answer I am getting the same response-" immediate return of flashcard for " hard and unable to recall buttons…same is happening for easy and good button which shows card will popup in 24 hrs!.. Anybody else facing the same issue please help as that should be different for different buttons. screenshot attached.

This is working as intended, assuming this is the first time the card is shown. Both “good” and “easy” set the next repetition time, with easy adding some ease for the repetition time after that. “Again” will show the card again from any state, while “hard” will show the card sooner next time. For the moment, minimal interval that is not immediate is 24 hours, so “hard” sees that it’s “harder” than 24 hours, so it must be immediate.

Thanks… i got it…
