User Manager 3.30 download limiting/queues

Ive just upgraded to OS3.30 Mipsbe on a RB493 and the download limits/queues for my pppoe customers dont seem to be working. Ive gone over all the configs and they all seem ok. I downgraded to OS3.28 to see if it would fix it but made no difference. Anyone have any ideas?
