Forgetting password on Notes

I have a couple locked notes and they were unlocking perfectly fine with my face id before I got ios14 but now only one of them unlocks with my face id and the rest is asking for a password which i have forgotten due to the fact ive been using face id a lot. I tried resetting my password but clearly that doesnt unlock my notes because they were locked before the password was changed. Can anyone assist me with this please?
