My traceroute shows my own router twice

So I got this fun little project running on a NAT VPS from OVHcloud, and I was tracing some latency issues to Hetzner's network. Running traceroute from my box, I see my own router's WAN IP at hop 1 AND hop 2. Same IP, same hostname pattern. I thought maybe I had a loop in my config, but I checked everything:

traceroute to contabo.com (203.0.113.45)
 1  192.168.1.1 (my router)
 2  192.168.1.1 (my router again??)
 3  10.45.2.1
 4  * * *

Then later, hop 4 just doesn't decrement TTL at all. It shows the same router for like 3 hops in a row. Is OVHcloud doing some weird tunneling? My nephew looked at it and said "the internet box is fine" but I'm not convinced.

Anyone seen this before?
