Many cards don’t conform the scheduled space-repetition 
although you choose easy button, it appears in my queue every day
it’s time to back to anki for space-repetiton, remnote is too unreliable to study
- Spaced repetition scheduler is buggy and unreliable
- Issue with Queue - Flashcards & Spaced repetition
- Incorrect next repetition time after answering hard
- Flashcards Bug
Btw, your issue is probably fixed by Huge problem in The Remnote algorithm, but it probably messes up the next repetition time. Since you got that card on Dec 6, I am starting to doubt that fix!!!
may i know how can I acess the card details you posted?
Thank you sir!
