Not necessarily a question but definitely a statement.
If you copy your notes, you cannot lock your note. DO NOT COPY AND PASTE into ANY note.
I just found out WHY I couldn't lock the note. I tested it with a note I could lock. For example, I can lock an address note. However, when I copied from another note into the address note, the address note would not lock because I copied into it.
Hope this helps!

Use Notes password-protection
Whether your note has an image, scanned document, or a list of important information, it's easy to keep it safe with password protection. You'll see a Lock iconnext to each note that's locked. Until you enter your password, or use Face ID or Touch ID, you only see the title and the last date that the note was edited.
Lock a note
1. Open the note that you want to lock.
2. Tap the Morebutton.
3. Tap Lock.
After you lock your note, it stays open and you'll see the Lock iconat the top of the screen. You can hide the note's contents when you tap the Lock icon
In case it should persist, then it would be best to connect with Apple Support: Get Support
Wishing you well, cheers.
