Fantasy LCS Roster Horribly Bugged

I tried to make some add/drops for next week. I moved a top laner off and tried to pick up another from available players, but I got an internal server error. When I refreshed, my top lane position was completely gone from Add/Drop (like, it's as if top lane doesn't exist on there anymore) and both top laners disappeared. I refreshed and my Flex pick disappeared from my ACTIVE roster, so I have one less player on my matchup this week. When I tried to replace the Flex pick with the same position (or ANY position for that matter), it said it would be invalid since I would have too many players in one position...which isn't true. I had one mid and one mid laner on Flex with none on my bench. I'm met with internal server errors whenever I try to fix any of this. Help would be appreciated! Thanks!
