RHEL7 Subscription Manager Issue

I actually have two questions here:

1 I had RHEL7 Beta installed, i removed this when i reinstalled the RHEL7-RC. Now when the subscription manager loads up, I see no valid license for the BETA edition [RHEL7 is green]. How can i remove this version from showing up?

2 I installed the RHEL7-RC. I was under the impression that this would not update to the GA version [there is two or theree previous posts with this information from someone from RedHat - https://access.redhat.com/discussions/915443].
However when I look in my subscription details I get the following, which looks like it did update itself [I hadnt been using the machine for a while, so only noticed this recently during a scheduled package upgrade]:
distribution.name Red Hat Enterprise Linux Server
distribution.version 7.0
distribution.version.modifier ga
Is there another way to check the version installed is RC vs GA? The redhat-release and kernel versions all seem grand to me
