Bug with Parrots Spawning in Jungles

I Have a survival world and it is in the jungle. Every now and then I go and look for parrots. I can only manage to find one or two every time. Apparently, Parrots are not spawning as much as they should be and i can only get more after exiting the world and then opening it again. This bug affects the latest version of minecraft bedrock for xbox one (Not the beta)
