Your wiki is a UCP wiki and there was an issue with renaming pages impacting the page count. See this thread. It is not clear from MisterWoodhouse's post whether or not they have/are running a script to correct the page counts that have already been impacted. Your wiki would seem to be proof that they haven't. However, any renaming you do now should not decrease the count further.
