Added route on F5 APM not showing up on my device

hello everyone

I added a route on our F5 APM, however I am not able to see it on my device. netstat -rn shows nothing for that subnet. I also check on F5 Big IP Client -> View details -> Routing Table my subnet is not there. I added my route on F5 -> Network -> Routes -> add and I choose gateway.

When I manually add the route on my device using sudo route -n add -net x.x.x.x/24 x.x.x.x it is working.

Am I missing something why my subnet isnt showing up? thank you!
