Bees not spawning

Put the summary of the bug you're having here

What I expected to happen was...:
I spawned a tree with a bee nest I hear the bees but they won't come out 

What actually happened was...:
i cant make a bee farm because they won't come out i had to break i then they did and i spawned another nest and still didnt come out but they went in and never come out again 

Steps to Reproduce:
1. get birch or oak sapling
2. use bone meal to grow
3. one nest spawns eventually but it doesn't work

 

i have also tried in an enclosure open world just anywhere copied my map off of my realm and triend it on creative still doesnt work i have waitng 3 irl days for bees to come out i can break the nest and they come but when i eventually spawn another nost and move them over they dont go in or if they do donmt come back out they dont take pollen from flowers i had around and make honey as you can see its not dripping
