OneNote Lack of Security for Locked Section

​The nonsense of not being able to password protect entire notebooks, only sections, is well known.

Whilst testing the free version to see if it meets my needs, I found some alarming loopholes in the section protection.

It appears that right clicking options, on a locked section, correctly prevents copying or moving it, without knowing the password.

However, the section name can be changed, or the entire section deleted, without the "insert password"  box appearing!

What sort of security is that?
