So, this could be intentional given how confusing it is regardless, but most of Hero Premiere Edition is double listed.
For example, HPE #1A and 1B is also listed as Star Trek: Deep Space Nine, Vol. 1 #1B and 1C.
HPE #2A is also listed as Batman/Grendel #1B.
These are all nicely numbered on the back covers as HPE #1, 2, 3… So in my mind, the HPE series makes sense. I get that people might expect the Ashcans in the individual series, though.
