Okay, I was making FP+ for the folks and me in Epcot on Monday, April 7. One of the choices was Living with the Land. 11:15-12:15 was automatically chosen for me. I changed the time to 11:00-12:00. But instead of changing it, it added another FP+ so now I have LwtL at both 11:00-12:00 and 11:15-12:15. Further, MDE even notes the two as "overlapping". I thought that was impossible. I know, must be glitch somewhere.
