Disable the plugin on some pages

Hello!
This is my question:

I have tried to disable the plugin on some pages of my website following the instructions I have seen in the configuration options: page name (with its slugs) separated by commas. I have indicated it like this: blog, access, contact
I have tried it in direct mode in reverse, but it does not deactivate. Do I have to do anything else to disable it?

Thanks!
