Is the RR use in MPLS-VPNs environment or just pure L3-IPv4/6 environment?
If it's MPLS-VPNs environment, then you don't need add-path.

Also if ORR is supported on QFX by any chance you might want to try that
instead of add-path.
Does it take the below? 
set protocols bgp group batman optimal-route-reflection
