Hi,
you have a problem......the machine is not Homing. If it were it would travel to the home switch, activate it and then back-off. It will back-off until
the switch de-activates. If it does not that means the machine is treating the switch as a Limit rather than a Home.
Try (in Ports and Pins) disabling that switch as a Limit and double check that it is assigned as Home.
