Same interval for all cards

Hey guys , i have a problem with my anki cards interval : it has changed and is now the same for all the cards ( it’s the maximum interval for all cards ) .

Check your deck options, or post some screenshots of the deck options screen.

Here are screenshots of my deck options ( i tried with default settings and it didn’t change anything ) :

Change the max interval from 80 days to something higher. The cards that you’re seeing the same number for all are cards that are too easy for you that Anki wants them to be 80 days at minimum.

yes but that’s the problem , it is the same interval whether it is mature card or new cards i’ve seen yesterday , it is the same interval for all cards . I tried to raise the interval , it doesn’t work . ( i used the rememorize add-on and suspected it to be at the origin of the problem but once i deleted it , it didn’t change anything ).
