Bamboo jungles inconsistently spawn pandas or sometimes have none.

All Bamboo jungles are inconsistent and buggy about spawning pandas opposed to other passive animal mobs.

how to replicate: Go to the same bamboo jungle for a specific seed and reset the region chunks over and over. The amount of pandas will always be partially random and mostly scarce as if the spawing code has something wrong with it. Other animal mobs are always consistent in number with each world resetper specific seed. In the above seed the bambo jungle will only ever have zero or one panda, and it's random every time the chunks get reset. This is extremely annoying anyway because a rarer biome that's already decently big enough should not have a odd random chance for having no pandas or having no way of breeding them.

side note: if results aren't seen immediately, try a world that has many pandas spawn in one area and a difference between resets will quickly be seen

In one intance: seed -1821522892755948386 between two nearby bamboo jungle biomes only one had a mere one panda, coords: (-570,-800) (260,-1215)

Resetting also showed random numbers each time. In one instance there were five total instead of one.

This means theoretically that a player might travel thousands of blocks in some worlds just to get none.
