I was changing one of our FP+ choices to another attraction but in the same time slot as one I currently had. The system never cancelled my original one and I can't seem to do it online. Do I have to call someone to have this fixed? I don't want to "double dip" or risk the chance that neither FP+ will work during that hour. So, currently, I have 4 FP+ choices for our HS day. Odd.
