Missions are now bugged

Ive been playtesting since around March and seen two major updates since then. Missions where introduced the last update around a month or two back, and worked fine up until the last few and then they disappeared. Since the official early access launch however, they are already bugged for me on just tour one, in the introduction of all the challenge types. It even shows I have completed the requirements but no matter how many times I restart or track and untracked the mission, its stuck on stunning 101 with all objectives completed. Quite frustrating how something worked better in pre-alpha than the beta
