Unfortunately, it looks as though you didn’t actually register for the season bracket.
All of our seasons require manual registration. So, in addition to creating a team and readying it up, you’ll also need to register for the season bracket. You can find out more from the Highlander hub, under How To Compete – https://tfcleague.com/highlander/
You should still be able to register, and will be included in the week 2 scheduling.
