HELP, trying to book FP+

[michelle06]

Trying to book my FP+ as I am eligible now that it's midnight. I am staying onsite and linked 5 day tickets. It says I am not eligible for the 5th day (4 days after I arrive) and I have dining reservations on day 6 and it won't let me book that day either. I thought I would be able to book 5 days worth of FP. Really confused. I did not book for our arrival day as we are getting in very late. So, I booked days 2, 3, 4 and thus have 2 days left on ticket. But it won't let me book any more days.
Can anyone help?

What is your checkin day? My date is June 1, but I couldn't book FP+ until April 2 or 3..can't remember which day it was. With some months having 31 days in them, it messes up the 60 days prior. But, it could be something else entirely.
