You can manually add the queues yourself.
Go to traffic shaper -> Wizard -> Single-LAN, Multi-WAN.
Key in '1' for number of WAN connections.
Select HFSC for both LAN and WAN. Choose 10Gbit/s for bandwidth.
Don't select anything in the wizard, just click next all the way.
When you're done, you should have:
WAN: qACK, qDefault
LAN: qLink, qInternet, qACK, qDefault
Now select LAN. Delete all the queues. Then add qACK and qDefault.
For qACK, set the bandwidth to 10%, Priority 7, Realtime M2 10%.
For qDefault, set Default, ECN, Bandwidth to 1%, Priority 3, Realtime M2 1%.
Go to queues tab, clone both qACK and qDefault onto WAN.
Now go to Firewall Rules,
under LAN tab, you will see a "Default allow LAN to any rule".
Click edit ('e' button), scroll down till you find the section that says Ackqueue/ Queue. Click the 'Advanced' button. Then select 'qAck' in the left box and 'qDefault' in the right side box.
Go to the Floating Rules tab now,
Click the '+' button to add a new rule.
For Action, select 'Queue'.
Check the box under 'Quick' section.
Under Interface, highlight 'WAN'.
Direction set to 'In'.
Protocol as 'Any'.
Source as ANY.
Destination as 'Lan Subnet'.
Set Description as: "CatchAll Inbound".
Set Ackqueue/ Queue as qACK/ qDefault.
That should be all you need to do.
