Short code content protection goes nuts

As an alternative to protecting content per level that I was trying previously (see this post: https://premium.wpmudev.org/forums/topic/cannot-get-summary-to-show-levels-more-tag-not-working-together ), I tried instead to do a short post.

While the short post code certainly works in hiding the content that it was wrapped around – the result is TERRIBLE!!!!!!

Have a look at the screenshot attached here…. The message is repeated numerous times – both in the space where I put the short code; as well as again and again at the top of the post (why, I have no idea????)

And to make things even worse, the pictures just don't show.

This is really just getting to be annoying as the whole reason why I am using WPMUdev is to get different levels with teasers for posts that get people to buy up a level. If I can't show teasers – or if I get garbage like this, I don't have a product!
