If the rest of your plants were in fine shape, and this one plant was "only" a double fan plus these pieces, I wouldn't complain about it.
Trim the fan back as Sue suggested, since pieces like this will tend to re-grow from the crown, often via the split in the existing fan. I plant "projects" like these in a good potting soil mixed 50/50 with perlite, and site them in bright, open shade, keeping them just moist.
Yes, the rest of the plants were great. And to be fair, the double fan of Banana Cream Beauty was a nice double fan. I would not have been disappointed in it. I have potted up the fan with the cut in it and it is in a light potting soil. I have it in diffused light in a location that I constantly walk by, so I can keep an eye on it. It looks good today. I cut back the foliage and removed a large scape and put it in water. The scape bloomed in the house this morning and it was beautiful in the kitchen all day.
Talking about "projects". There were two tiny fans of something rolling around in the box. I potted them up, too. They will be a surprise since I don't know which cultivar they belong to!
