How possible tow Route policy with same parameter with Hit count > 0 on second one

[mtc]

I found on our FortiWiFi 60E FortiOS v6.4.4 build1803 the follow lines:

As you can see, all traffic from Lan subnet already route to wan2 by policy 39. 

So how it's possible Hit-count (>0) for policy 35?

(I clear all Hit-count before i take above snapshot)

Do you have any link monitors or sdwan performance checks that are set to remove routes when there is a failure?  

If you clear all sessions on the firewall do you see the same behavior?  Could be an existing session using wan1 still.  

di sys session clear

[mtc]

Thanks reply me.

Link-monitor. did you mean to Performance SLA screen? No there have nothing.

I check it after I made restart. I supposed it's equivalent to clear sessions.

Could you share the configuration you have from the CLI of the link-monitor?

[mtc]

yyy-j2 $ show full-configuration system link-monitor
config system link-monitor
end

yyy-j2 $ diagnose sys link-monitor status

yyy-j2 $
yyy-j2 $

Sorry without seeing the full configuration and running some diag debug flow filter commands to see the decisions that are being made by the Fortigate it would be hard to give a definitive answer.  Your best bet may be to open a TAC case to help better understand it.
