You are right, here are the dates from previous years:
madden 19 release: Aug 7 series 2 = Sept 21 series 3 = Nov 2 series 4 = Dec 14 madden 20: Release: Aug 2 series 2 = Sept 20 series 3 = Nov 1 series 4 = Dec 13 madden 21: Release: Aug 28 series 2 = Sept 25
It looks like they want to keep the same series schedule as previous years, despite the game being released later.
