Anon, it's been like this since OOO.
Because of the schedule change since W, they're technically celebrating the franchise anniversary with 2 shows; OOO and Fourze, Ghost and Ex-Aid, Saber and Revice, and now Zeztz and Reiwa 8th.
The later of the pair are the one who premiered with anniversary logo, but the prior still celebrate in a way since their January episodes.
