Hi,
When sorting the checklist view based on "Release Date" collumn, the newly added extension pop on top of the list (screenshot bellow). I think it's linked to the date format for the year (21 instead of 2021)
Not a big deal as there is only 3 new set with this date format right now ;-)
You're not dumb fella, lots of things to keep track of in the app and you're doing a great job.
