mtr only shows last hop

Hello, I am not sure if this is the right place to ask but when I do mtr I only see the last hop. I tried different domains even domains from other countries and I only see the last hop.

The only time I see all the hops is if I do mtr with -T (tcp) or -u (udp), but then most of the hops are all question marks. mtr with icmp used to work before.

My gateway/firewall is centos7, I disabled firewall to see if that helped but it is still the same thing. If I do mtr from vms or my laptop on the LAN then I see two hops, one is the the LAN GW and the the last hop.

I don't think this has anything to do with centos7, I am using Verizon FIOS, so I am not sure if they are doing some weird stuff, if that is possible. I was hoping someone here would know a technical explanation. Thank you :-)

From my laptop:

sudo mtr google.com -rn
