Export two static routes - one with higher local pref

Hi I currently have one server with dual connections to two PE routers. Each server is using a loopback address which is reachable via a static route on PE1 using default metric 5 (primary route) and via PE2 using metric 254 (backup route). My intention is to export these static routes to all other PE routers (MPBGP) with the PE1 originated route tagged with local pref 150 and the backup via PE2 tagged with 100. Problem is I don't see the backup route via PE2 on any other devices and only see the primary route via PE1. Anybody know any reason for this? (note all of these routes are contained inside their own VRF) \#BGP \#MPLS
