Cursor rules not working at all

I added rules from the setting of the app and I also tried generating a rule file with one of the AIs, it worked I got a rule file but no matter what the setting is set to it did not work.

I tried adding the file using @add-context but it did not work.In other words the AI did not even see the file and I also used diffrent AIs like clude and gemini and diffrent models, but no matter what method I used nothing changed.

The only thing that worked was that I went to the rule file I selected all the contant and then copied and pasted in the AI chat and it worked.
I tryied using .cursorrules file too but it did not work either.

what can I do? Am I mising a setting or something?

I also tried reinstalling the whole app but notthing
