Babies Don't Grow Old! 😱

When i built a VILLAGE & PILLAGE villager breeder I tried. After 5 minutes, none of the babies grow up to adults. They also walk away from the parent or village. I also tried to increase the random tick speed to 1000. And yet after 10 minutes they still don't grow up. This is very annoying because I want to transport villagers to my villager breeder in survival mode. Please hurry, my server is commencing OPERATION MOVEMENT & OPERATION RIVERTON.
