My apologies if this was confusing to anyone – this post was for the paid “Portal” add-on, not for the base Our Team Showcase product, and as such should not have been posted here.
Smartcat got back to me right away directly and I had a fix in place shortly after I posted. I just got back to work and so am now posting this update and closing this thread.
For future information if anyone else has this issue with another add-on, what I did was add the code do_shortcode() in the file doing the output. In this case it was in the post.php file.
