You haven't done anything wrong, they changed calculations.
I can't remember last time I used formation with 3ST. I usually play with 5 or 6 mildfielders, sometimes with 4.
It doesn't explain why it is now an illegal formation. And also I use long passing so i don't need a strong midfield. I have not lost using this formation this season
