User List Repeating

I am first and foremost sorry if this is the wrong forum for this, but we seem to be having a problem with our user list.  It does not matter if I am looking at the regular user list or use the search method under administration.

What is happening is the user list does not properly display each page.  Or to be more specific it repeats 90% or so of the users from the previous page then adds more to it.  It keeps doing this over and over.  Each page seems to become longer as well or something.

Easiest thing to do is simply go to http://forum.gamebreaker.tv/userlist.php and take a look at the user list.  Look at page 1, then click page 2, then page 3, then page 4.  Notice the length of the page increase and it starts to repeat all the users from the previous page.

I have no idea what is causing this and would like to figure it out as moderating/administrating the forums becomes a hassle with this issue as well as we have no idea what our actual user count is.
