Live Tracks still auto starting even when disabled.

I used Live Tracks on the weekend with the auto-start feature and it worked fine. I have now disabled it via the app and directly on my Edge 540 but it is still auto starting.

When I disable on the app it correctly syncs the status to the device but it is not actually disabled. How can I fix this? 

I removed all contacts but auto start still starts live tracks. I saw a similar post on the Edge 1040 series but with no response - is there a solution?

Thanks
