Unable to heal in any pokecenter

After I got to Gaea Town, my Pokémon were with low health, so after exploring the place I sped up to go to the Pokémon Center. I interacted wih the nurse and she just says "Hello and welcome to the Pokémon Center!" and doesn't heal my team. I attached a picture for you to understand what's happening (if that's relevant I use insane speed)
