Shortcode with Membership Plugin Not Working as Intended?

I don’t know if I am better off posting an issue with shortcode or an issue with protected content, but shortcode is easier to illustrate. Can anyone explain why shortcode in the following example functions for visitors but not for my only other access group? I tried this route because the content illustrated was not being protected as intended.
