SDWAN Issues 6.0.4

Hi, I have a FGT on 6.0.4 version and have varius issues with SDWAN: - Some times not apply the SDWAN rules and the traffic is going by default SDWAN rule. - The default rule has 3 interface and has a volume balancing with a interface has 255 and other two have 0, some times the FGT send traffic to interfaces with priority 0. - Some times any website said me TLS error and other time working, when this working, I see on traffic log that source and destination interface is "unknown-0".   Thanks!
