Queing rdf saves the instances?

If I could post a photo I would, but who knows why that is am certain that queing rdf heroic randoms does not save you under the specific tab.

i queued yesterday for specific instance, it popped up but somebody didnt take it and it didnt queue me back and also i was saved for that instance which was pretty fcking stupid

Doing RFD for Heroics does save you to the instance. I am pretty sure this is expected behavior. I think it was at a later expansion they removed it.
