Just a guess, but I think it shows that when they are running the bids for next month. I had the same issue for about 10 minutes earlier, but it's working fine now. Since the daily trip coverage page has changed recently and now shows all trip awards (swaps with the pot, white slips more than 1 day out), when they run the bids for your category and all the trips initially get awarded, it's probably too much input for the system to handle for display.
