Bright House ISP routing private IPs on the Internet

Recently I found our ISP (Bright House) is routing private IP addresses publicly. Has anyone else run into this?

We have a network ID of 10.10.12.0/24 internally. For some reason when I do a tracert to other 10.10.x.0 networks and some 192.168.x.0 networks I can see the packets are being routed through our firewall, through our ISP's network and into someone else's private network. I can even connect to devices on these remote network by private IP using HTTP.

Bright House has explained that they use 10.x.x.x addresses publicly and don't support clients of theirs using 10.x.x.x network IDs in their private LANs. Has anyone else run into this?
