There are a couple of reasons that this might happen.
But what is comes down to is the first two routers are not sending icmp packets back to the MT. can you ping the two routers directly? if not then they are set to ignor ICMP requests, but still forward them. this is most likley the case.
Other times companys will uses non-public addresses for hops allong thier private network. this works because the routers only care about the next hop and not the path. You will see this often in traceroutes accross the internet.
Most major providers block all trafiic from non-routable IP’s
