Zombies and Creepers spawning in well lit areas

Zombies and creepers are spawning throughout my town no matter how well lit the area is, both inside and outside of buildings. Incredibly frustrating since I keep adding more and more torches and jack o lanterns everywhere and they keep spawning and killing my villagers in my fenced-in village. Mobs did not used to spawn in these areas and I have made no changes to them in months that would have changed the lighting to be darker. No idea how I am expected to take screenshots on a PS4 so i have attached some pictures of my TV sorry for poor quality
