To be honest I don't see where the problem can be. I'd recommend you to open a support case. In addition you can add an irule to log information about the load balance decissions, active members, etc:

when LB_SELECTED {
  log local.0 "Active members: [active_members [LB::server pool]]"
  log local.0 "Pool member: [LB::server addr]:[LB::server port]"
}

A packet capture will help to see what is happening underneath, destination mac address, etc.

Sorry to not be of more help.
