IQ2 PIC supports only one "strict-high" or "high" or "medium-high".
Please modify your configurtion,

We hit a similar issue in the past, on an M320 with an IQ2
10Gbps PIC as well.
Basically, you cannot configure more than one 'strict-high'
or 'high' scheduler for an interface. The router will commit
only one of each for only one interface.
In a way, it sort of makes sense, since there's no point in
scheduling traffic with priority on multiple queues on the
same interface. It would defeat the purpose :-). Also, the
only difference between 'high' and 'strict-high' is that
'high' respects the 'transmit-rate', while 'strict-high'
does not.
I can't recall whether the behaviour was different on the
MX, but we decided to go with the least common denominator
so we can have configuration and behaviour consistency
across the entire backbone.
Cheers,
Mark.
