It does not let me activate the OEM unlock

Hello, I want to mark the OEM unlocker to be able to open the boot but when I activate it and go to the previous menu it is deactivated.

What is the reason and what solution is there?

Thank you

Solved, to leave the OEM Unlock button activated, keep pressing on the letters until it indicates if you want to activate it.

Thank you all
