Multi sensor contact not updating

Hi, I have a zwave multi sensor which has a door sensor (magnetic read) which is updating fine in indigo but doesn’t seem to translate to HomeKit. I’ve got it set as a contact sensor. Have tried using invert state no joy. Is contact sensor the right kind of device.

I meant to also say thanks for the HomeKit plug-in. I use it with a house load of z-wave devices, it works very well.
