Im in a WDA league. The player I was supposed to play and myself were having issues with the site running slow and having to constantly refresh the page to get it to work, so we decided to reschedule for the next day. But  now it will not allow myself to delete the old start time and when I try to make a new start time it says it conflicts with the old start time. the old start time does no longer appear in the drop down match menu. What can i do to fix this?
