simple failover without load balence.  

WAN is fiber

WAN1 is cellular.

WAN1 a verizon monhtly with limited data.  I cannot find the settings to stop the router from constantly using data on it.  Load balenceing is turned off.  The failover works as we have sadlt had to use it alot this month after a car accident took out the whole blocks fiber connections. But why is such a high percent of my total data using the wrong WAN.

Picture is after a clear with 1 minute of 9am traffic which is the lightest part of the day.

thank you
