Unlock notes iPhone

I locked some notes on my phone but for a few weeks now (can’t remember which iOS update it was) I can no longer unlock it. I tried resetting note password in the settings but it won’t work. Every time I try to open it goes straight to password (it doesn’t allow faceID) and no matter what password I try it fails to unlock. Some of these notes were quite important to me and it would be upsetting to lose it.
