Media Numbers Wrong

I installed/uninstalled some themes yesterday, testing things to see what would work for my project. At some point I installed the theme Video and it had a bunch of dummy media files… now that I’ve uninstalled it and gone a different route theme wise, all my media numbers show that I have hundreds of images and I would like those number to correctly reflect the amount of media files I have uploaded (7).

I’m not positive the Video theme screwed this up but I did go onto my server and delete some files that theme had installed under a folder called dummy. The numbers still reflect the wrong amount of media.

How can I force WordPress to look and see how many media files I actually have. It’s like it needs to run something and check to see the other files are gone.

Thank you!
