The two in the middle of the cup look like aefw, centers have a lighter shape in them and the outside edges are clear with spots where they blend into the corals flesh. We need to see a picture of the coral though there could be no real damage to the coral and the flat worms just got on to the coral before it was bagged.
Cutting everything but the growing flesh is a start, but if you can't I'd an aefw, your never going to find it's eggs... they can hide right along the growth rim of the acro so you can barely see them. Sneaky buggers is what they are. If you don't have another tank to isolate them in and keep an eye on them for any signs of aefw then eventually one day you will get them if your always buying coral.
I have got them from the most respectable online vendors, ones that people would swear by, and say they have perfect qt practices. And got them from the most reputable big hobbiest sellers on this site. Sooo, it's going to happen. Treat everything like it's infected.
