Problem with PCQ after upgrade to 5.6

We have 2 RB750 with NAT and DSL Line 30/4 Mbit/s on ether1
The Board is doing QOS with PCQ, everything works fine on 4.6

We upgrade to 5.6 because the new feature pcq-burst is very interesting for us.

After Upgrading from 4.6 to 5.6 all Upload Traffic goes into the 1M PCQ Rate, when i start 4 uploads from 4 different PCs then upload is on each PC 256k. Not 1M for each PC.

PCQ Download Rate 2500K, Upload Rate 1024K with Queue Tree Max 25M / 4M (Down/up)

/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=yes limit-at=0 max-limit=3800k name=upload parent=ether1-gateway priority=6
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 max-limit=25M name=download parent=ether4-local-slave priority=8

/queue type
add kind=pcq name=PcqDown pcq-burst-rate=2500k pcq-burst-threshold=800k pcq-burst-time=2m pcq-classifier=dst-address pcq-dst-address-mask=32 pcq-dst-address6-mask=128 pcq-limit=100 pcq-rate=1200k pcq-src-address-mask=32 pcq-src-address6-mask=128 pcq-total-limit=2000
add kind=pcq name=PCQ_Upload pcq-burst-rate=1024k pcq-burst-threshold=500k pcq-burst-time=1m20s pcq-classifier=src-address pcq-dst-address-mask=32 pcq-dst-address6-mask=128 pcq-limit=50 pcq-rate=700k pcq-src-address-mask=32 pcq-src-address6-mask=128 pcq-total-limit=2000

And another thing I noticed in 5.6 when I start torch on ether1 (10.0.0.1) I cannot see the traffic from the dsl Modem (10.0.0.138), the router “sees” only its own traffic. On 4.6 you can see the traffic with correct Dst. and Src. Address ?!

Cause most probably it is a configuration error. There are only bits and pieces of information - lots of relevant data is not here - how are your interfaces configured? Bridge? Switch? how does your NAT looks like? what other queues do you have.
