PPPoE Server, Mikrotik-Rate-Limit and queues working only in one direction.

as in title, queues set from RADIUS on 7.2rc7 running on CCR2004-1G-12S+2XS are only queuing traffic in one way (towards the customer, i.e. rate=0bps/82.7Mbps in /queue simple print stats)
since the queues are dynamically created by routeros, and created from RADIUS settings, I think I may have stumbled upon some bug.

Note, that all PPPoE traffic is routed via VRF, and all PPPoE interfaces are assigned to a VRF using /ip vrf set (…) interfaces=(…),dynamic and traffic is passing flawlessly and as expected.

Any ideas?

I stumbled upon the same issue. If you turn off the VRF, then everything works perfectly. The problem is VRF.
Did you manage to solve this problem?
