New Netherland names are confusing to modern Americans because New Netherland settlers didn't follow modern American naming customs. But WikiTree tries to identify people by the names they actually were known by, not the names we think they ought to have used. This means looking at the original records for the person's name -- not later genealogical publications that treated all of the author's paternal ancestors having had the same surname as the author.
When Hendrick (Epkese-1) was born in the Netherlands, most Dutch people were known primarily (or more often, exclusively) by patronymic names. That seems to the case for Hendrick. (I'm not familiar with this family, so I'm going by what I can see in the profiles.) His father's given name was Epke, and from his profile it appears that all of the original records for Hendrick show him using Epkese, or some other patronym derived from Epke, as his last name. The name Banta was adopted later.
I also don't see any indication that records show that Hendrick's father, Epke Jacobs, ever used the name Banta.
And since Hendrick apparently was using a patronymic name at the time his children were baptized, it stands to reason that his son was called Hendrick Hendrickse (or variants like Hendrick Hendricksz) at the time of his baptism, although he might have adopted the name Hendrick Banta later in life.
