Object Tag - Changing Layer ID's doesn't work!?

[buffmotion]

Please can someone help, this is driving me nuts.

All worked in the past, then updated. Now when I select the chosen layer ID on the Object tag, then go to select it in the pass settings, nothing renders.

I just want white mattes. Now there is an 'instance ID' since updating? Not sure if this is anything to do with the issue but am struggling to do something really basic.

Yep, it's setup just as I always used to via the render layer mask IDs.

The tag has the ID number selected...

And I have setup the render as it should be right?
