which is weird to me, because isn't that supposed to happen every time?

Nah, the species of the host remain after transubstiation normally, as in the physically observable qualities of the bread and wine. The transubstiation happens metaphysically, which only makes sense if you detach the meaning of an object "being" something (being bread or being the body of Christ in this case) from what you observe physically. The thing that sets the eucharistic miracles apart is that both the physical and metaphysical parts of the host are transformed.

Makes sense though, if Catholics always expected the bread to turn into a bleeding piece of flesh then it would make Mass very disappointing when that hasn't happened in a regular Sunday Mass in 2000-ish years.
