Noticed this when I started testing for the release, since the release VM has everything enabled. There's an ingest step associated with Populator (screenshot attached) that gets inserted as the first step every time you add an object through the GUI. It's fairly confusing unless you want it there.
It should have a note right there in the GUI saying that it comes from the Islandora Populator module, where it can be configured, and that it can be skipped.
Also needs to be documented in the wiki, of course. But for the end user, having an ingest step admit where it comes from would be very handy.
