approved reviews not listed in admin

Hey there – we’ve got 3 reviews in our WPCR — one was pending and could be seen on the backend, two had been approved (and the ‘Approved (2)’ was listed across the top) – however clicking on that shows an empty list.

I can’t delete them nor edit them in anyway; would it be best to just go into the mysql and delete them via post type and try again?
