Shadow Tasks for Shadow Leveling keep Disappearing

For two weeks now when the week resets the Shadow tasks that we do to upgrade our Shadow rank has been greyed out. It shows that I have done everything except for Path of Blood and Vault chests. I had not completed the rest of the list, and while I am locked out of the choices I am unable to complete any of them, and therefor unable to level up my Shadow Rank. I play virtually every day, and I need this repaired so I can further my rank and keep up with my clan. Please help. Thank you.
