Level shortcode doesn't seem to be working correctly

I saw a similar issue here https://premium.wpmudev.org/forums/topic/membership-level-shortcode-and-protected-content, but didn't see a solution available.
On my "Content Protection Options" tab, there are no shortcodes listed, contrary to the Manual. I'm assuming that the feature was considered redundant and removed?
Thinking so, I entered shortcodes according to the instructions in the manual, but am not getting the desired results. For the level I'm on, I get the message I want. But it also includes the "You're not supposed to be here" message for all other levels. When I register as a friend (basic free registration) I get:

Welcome Friend!
Oops! I don't think you're supposed to be here. It might be best if you went back the way you came. Or maybe you need to upgrade your subscription? Thanks!!

The "Oops" lines represent the next three levels. When logged in at each level, that level works fine, but it still shows the "Oops...." for the other three levels. You can register as a friend at http://tradingpits.net/register/ and see what I mean.

Thanks,
