All Testimonials page has no content though showing “Published (8)”

Hello,

I installed the plugin a couple of days ago and published 7 testimonials in two rotators and it was all fine until I opened my website the next day and found that no rotator was showing though the code was still there. No testimonials were appearing and the rotators seemed empty.

I tried to start over but I found out the slug was getting a (2) added to it as the first copy is still there somewhere though I can’t see it.

When I go to the “all testimonials page”, I find nothing but the one I recently added. But it still has the following on the top left corner:
All (8) | Published (8)

I tried deactivating and deleting the plugin then installing it again, but I get the same result. There are still 7 testimonials that I can’t see, plus the one I duplicated when I tried to start over.
