It's just a couple of edge loops being very close together. I wouldn't even sweat it. I did notice that the included templates for Antonia were shot from the low res version. Probably I could have found medium res versions (snow sultan perhaps, or 3dream), but I just used mudbox. It generates a transparent template layer overtop paint layers when you bridge channels to photoshop. There's a bit of juggling though with mudbox, it's UDIM by default. Older figures are overlapping UVs...
