vSphere Replication error "There is a storage issue with datastore path"

I can't get passed this error "There is a storage issue with datastore path" when I try to replicate VMs from my protection site to replication site.

I have looked at the blogs and KB: 2040302 article.

But I don't have two management networks on my hosts.

I am running vCenter 5.1.0 build 1364037 and ESXi 5.1.0 build 1065491 with SRM 5.1.1 Build 1290726 on both side.

I am using virtual distributed switch on my protection site and virtual standard switch on my replication site. Also my VR server are on a different network them my host management. 

any ideas?
