Week 1 challenges showing as not completed, completed them all

As seen I do have 10 of them completed, so it should be showing 10/10 and have the green tick on Week1.
I have also seen some people having 11 of them for week 1? I do have 11 of them for week 2 but not for week 1. Unsure if it's related. But I did make sure to do them all.
It's bothering me cause of OCD but otherwise not game breaking
