Slime spawning issues PS4 bedrock.

PS4 bedrock version of the game has extremely glitchy slime spawns. I have a 6 platform slime chunk and a swamp biome farm, neither work and i have to spawn in and out of the world multiple times to get a initial spawn but then it stops again after 2 or 3 slimes. So the locations for slimes are correct they just aren't spawning correctly.
