Canon 1DX Mk2 beyond focus range

I have an odd focus problem with my 1DX mk2 regardless of lens in use.

The shutter button is set for Start Metering (CFn 6) and use AF-ON back button focusing.

Camera is always on AI Servo & most of the time this is fine, but occasionally the camera will be "beyond" focus range and won't come back. When I press AF, I can hear the lens try to focus and the Focus indicator will constantly blink on the bottom row.

Once I pull the focus ring back to get in focus, it will lock on fine and work perfectly, panning will snap on sharp on the relevant selected focus point.

As mentioned it does this with the following lenses:

Canon EF 100-400mm f/4.5-5.6L IS II USM

Canon EF 300mm f/2.8L IS USM

Canon EF 500mm f/4L IS USM

Canon EF 600mm f/4L IS II USM

I've wiped the camera contacts with a clean dry cloth.

Is there a setting I am missing or is it a faulty body?
