Previous beta version had a warning "Some Object Masks are Offline and will be ignored" That version was only ignoring the mask, not the layer itself. 

I've saved the project differently and updated to the latest beta version of the After Effects Beta. Now there is no warning but render preview shows that layer with the new AI masking is ignored completely.
