Ghast Spawning Bug

Hi! I noticed that the ghast spawning mechanics is really broken in bedrock because even when I switch to easy difficulty it spawns too many ghast at a time. I always get like 2 ghasts spawn at me at the same time and place and when i kill them both another 2 would spawn on the exact location. Sometimes it would glitch out and even though I completely see the entity, I cant shoot it with projectiles. Pls fix this thanks
