Contributors Page Innacurate After cvs2git import

We used cvs2git and everything worked great the history is there for each commit each and it lists each users associated to the commit.
However the contributors page shows only 1 user made all the commits. These user that it lists doing all the commits is the last user that commited via cvs.

git shortlog --no-merges -6000 -nse
shows each individual commit done by each user

and going to the contributors page and clicking the history button shows each individual users commit.

But the summary page only shows 1 doing all 1600 of the commits on this project.

Is there something I can do to fix this?
