Packet dropping is normal if you are going to shape traffic, but that is not
so significant,
in your case there is quite big number if dropped packets, but normal
anyway.
thi can be because you are shaping udp traffic, which do not have rate
controll ability.

you should either pass all udp packets, either ignore wasted traffic.
