[Plugin: Paid Memberships Pro] PMPRO shortcodes

I’m running 1.5.1 of your plugin.
I’m having a problem with [membership level=”0,1,3,4″],
the restriction causes the shortcode not to load because maybe show excerpts is on?
it works for any logged in member but not for non-members. I did some tests and I know the shortcode is not loading because I put echo’s in the shortcode function you put in the main .php file
