Dynasty Custom Schedule Error

Cannot make any custom schedule changes in an online dynasty. Was able to do so in year2 offseason but can’t in year3. Even just changing a road game to a home game says there is an error and it doesn’t work. Crazy that this is an issue and even worse there’s no fix. Can’t seriously expect people to restart multi year online dynasties because there’s no patch for this? We don’t have any custom conferences. Just normal base conferences haven’t adjusted any conference settings.
