        Without more details of your configuration - it makes it very difficult to troubleshoot.
        Please goto network (1) - self ips (2) and check your configration for proper traffic group configuration.  

        I use my naming convention to call out purpose.   i.e. -
        LoadBalancerName-Vlan-Self = traffic-group -local only <---this is suspect is what you have and is causing the error.   This as a self - belong to the individual f5 and will not failover it stays the same.
        LoadBalancerTG-Vlan-FLOAT = traffic group that is responable for failover - hence will float from one side of a ha pair to another, i suspect you are missing one or more of these.

        I drew some lines on mine -and colorcoded them to show you the selfs - and the floats and the traffic groups etc.
