APs disassociate when WAN failover happens

we have a number of remote branch offices with HREAP access points. Each  office has an MPLS link back to the main office where the WLC's are.  We have IP SLA setup on the switch so that when the MPLS link goes down, a VPN tunnel is built over the internet link via the edge ASA.  All routes are handled via OSPF.

The problem is this, when the failover happens to the VPN, everything reroutes correctly but when the MPLS comes back up, the access points dont reroute, they continue to try and talk via the VPN tunnel.  I have to power cycle each one to get it to rejoin the WLC over the MPLS. 

Anyone know why this might happen? thanks
