Can't get rules to work for /admin folder

I am using an opencart store, and in my admin section Cloudflare are giving my a couple of issues.

In one of my extensions I am getting an error saying that I do not have permission to modify it.
In my orders I can’t update the order status.

When I disable Cloudflare everything works fine.
Here is my rules domainname. com/admin Disable Security, Security Level: Essentially Off, Cache Level: Bypass, Disable Zaraz, Disable Performance

Is there anything else I can do to make Cloudflare completely stay away from my /admin folder?
