[2020] [Missing Content]Raid keys and chests

I have been having issues with opening raid chests during the last week however it could be solved by leaving and rejoining the raid. However this morning I joined my team on iron horse after reset and all the key chests were open on my iron horse run and the exact same issue in Dark Hours this afternoon. So I currently cannot get any raid keys with the exception of the boss drop can anyone help with this?
