LCM in SAP BO 4.0 Webi not using new Universe version

Hi I am trying to use LCM in SAP BusinessObjects 4.0 sp5. After moving a universe from a development server to a production server using LCM (promotion management) everything seems to work as advertised: connections stay the same on my production box, security stays the same, and I see the change when I import the changed universe on production into universe designer. However, in order to see the change in an existing WEBi report or a new WEBi report that uses the universe,  I have to export the universe again to the production server from universe designer in order to see the change in WEBi. Note that I had tried first logging completely out of BI Launchpad and logging back in, but that didn't help. Any ideas?
