Are cached references automatically not filled?


I was wondering if cached references could be filled?

I have this reference, and while set to dynamic, it is filled, but the moment I switch the reference to cached, it drops the fill. Is there any way to leave it on. The display style of the view and reference are both set to hidden line.
This is the dynamic view:

And this is the cached view:

With kind regards,
