Drupalexp Module changing reported Core version Number

I am having a problem with the Drupalexp Module changing the reported Drupal revision from the current most up to date (Ver 7.31) back to version 7.27. Thus my Drupal install is reporting that I am using version 7.27 when in fact ver 7.31 is loaded. This is turn is causing other modules to not function correctly because it is reporting an inadequate revision number???
Hi, Drupalexp Module does not change anything in Drupal core and version report. Did you run update.php? Thank you.
