Allowed websites being blocked

Hello, I just installed Norton Family a few days ago. My issue is that I blocked all categories and then placed the allowed websites into the allowed category and saved. The websites show up in the Allowed websites section of the "house rules" but the site is still blocked.

We are using Win 7 And the chrome browser.

We MUST use the chrome browser because it is the only one supported by the virtual schooling website.

Thank you for any help.

 

****** Let me add that this is not the case for EVERY WEBSITE only certain ones. 

For example we are able to block entertainment and music but still access Pandora since it is in the allowed websites. But if I block education and reference we can not access the school sites, even though the are in the allowed website section.

Do I need to do it in order? For example, do I need to block all categories and THEN add the allowed? Because thats the only thing different I did with Pandora.
