I am using, or trying to use the membership plugin again

I created levels, I created subscriptions...

I created a page, want it protected, but I can view it on the other browser...with no subscription.

I see where it says, make sure the pages you want protected are not there, but that's what I want for that subscription...it does not matter because whether checked on or off, it still shows.

So I just randomly choose, silver level, created a silver subscription at 9.95, put the level under the subscription, and still nothing...there is no way to protect it, if it is, I cannot see it
