BUG? Strange traffic coming from disabled ipip-Tunnels on RouterOS

On my main router I have 3 ipip-Tunnels that go out onto my wAP LTE Kit and out the LTE interface as I have tunnels that go to 3 of my other routers that are only reachable via the LTE
I have OSPF enabled on all my routers and currently my LTE and all ipip-Tunnels are disabled but I am getting traffic trying from my main router (10.0.1.6) to each other router but is unreachable as the LTE interface is disabled on my wAP LTE KIT, this only happens when I allow default-route(0.0.0.0/0) on my wAP LTE Kit which then gets it from the main router.
My main router then sits on 100% CPU consumption and this is all happening when the ipip-Tunnels are disabled. Bug?

All routers are running latest RouterOS(6.42.7), main router is RB2011UiAS-RM
