Traceroute show only destination HOP

Hi, iam experiencing small issue on LTM (12.1.2) with traceroute/tracepath when i use default outgoing interface. We need to debug a path to some world destination, but traceroute/tracepath shows only destination HOP not a full route. Like:

[root@lb008:/S1-green-P:Active:Standalone] config  tracepath f5.com
 1:  f5.com (104.219.107.168)                             179.061ms reached
     Resume: pmtu 65535 hops 1 back 243 
[root@lb008:/S1-green-P:Active:Standalone] config  traceroute f5.com
traceroute to f5.com (104.219.107.168), 30 hops max, 60 byte packets
 1  f5.com (104.219.107.168)  183.391 ms  177.893 ms  183.425 ms

I have tried ICMP, TCP but still same. But when i choose mgmt interface, which is connected to another network and directly connected to internet, i see full route.

Have someone ever had similar problem? Thanks
