"Weekly Objectives" offers 1 challenge per week. The only active challenge is the top-most challenge in this section, and it will tell you if you have cleared it or not. Keep in mind that it will not count if you unsync these challenges.
"Mini-Mog Challenges" offers 2 challenges per week. The only active challenges are the top 2, and it will tell you whether you have cleared or not. Keep in mind that you can only complete one of these 2 challenges; once you complete 1 of them, the other will no longer be available.
