Does comcast have somthing setup in their routers wrong since it is routing this private ip space?

Welcome Lee. The Comcast gateway routing schema for static ip's is RIP V2, for the D3 gateways the Cable interface has the source IP instead of the WAN interface. I can check the gateway configuration.
VIA PM (private message) please send me the full trace data, the MAC Address of the gateway also any info on the hierarchy, ieC>>switch>>router>>gateway. Etc.. Also are you testing from you private IP space to your public IP address?
Thank you
