I am trying to sniff wireless traffic on my wireless network and an running into an issue with malformed packets. When I am sniffing the interface in managed mode I see traffic coming through correctly with no problems, however when I switch to monitored mode almost everything comes through as a malformed packet.

"Malformed" where? Is the packet mostly OK, or does it show up as mangled from the beginning (or from the beginning of the 802.11 header, if there's a radio header before that)?
