Permissions do not work for Woodmart HTML Blocks

Hello,
I am using Woodmart theme.

I want to make an HTML Block where only the “Customer” and “Not Logged In” roles can access.

I create the HTML block and then add it to the corresponding page.
All roles have access to this PAGE.

The result is that the “HTML Block” appears in all roles on this paage.

Am I doing the process steps correctly?

Thanks
