QBI rental properties not able to aggregate if i take enterprise safe harbor

I have several rental properties. When I am entering QBO section, and elect the QBI safe harbor as an 'enterprise' as shown in this screen..

Then later on on aggregate screen, I don't get an option to aggregate it with properties. Only option shown is that it is independent.

However if I take QBI Safe harbor for individual property then I get option to aggregate the properties on aggregate screen. Is this a bug or somehow they are linked and this is correct behavior ?
