Doesn't save Hook settings

I sent you earlier login details - login and password
The very first link is a link to the Hook

Hook - Shapka_H1

Try to add any specific page, or page category - to exceptions

Actual problem of creating an exclusion rule in hook Shapka_H1
Exception - page category

Yea, I can see it happening there.

However, I added the exact same post to the "Test" Element and it works.

Have you experienced this issue with any other Elements, or only this one Shapka_H1 Element?

If it's only this one, we need to look at why it's different. It may be worth re-creating it and adding the Display Rules one by one to see if there's a specific rule that is breaking the functionality.

There were no problems with hooks before.

Thanks for the advice.
I will create a new hook as a take

Created a new hook with a different name, everything is saved in it.
Thank you for your time.

Very strange - glad it worked. Let me know if it happens again.
