So I was just doing all the challenges to 100% this game. The Truth challenges told me i had some side missions to do. These challenges of course are main and side missions in a region. For this bug I will be using the Archipelago region. This is not the only region i am having this problem but it is the first. So this is what it shows.
It show i have one mission left to do. Unless you can skip main missions this means it is a side mission. Now for example how it is supposed to work My friend has all the Truth challenges done. Now to complete 18 main and side missions. each dot is 6 missions. 6X3=18. Now this is also weird. It says you need 18 missions done for the challenge. But my friend has completed 17 missions,(he triple counted), Including the intro mission. So he is one short but has the challenge done. I have the exact same amount of missions done, and am one short. Pics below:

The Archipelago missions he has completed,(including the intro mission)
I have completed all these missions as well. We have triple counted. This thing is also happening to other regions in theses challenges
