Creeper spawns in realms are higher than in a normal world

Creeper spawn rates are much higher when on a realm. On a night, 8 creepers had  spawned within 6 minutes of it being night with 5 spawning within a 32x16 radius and 3 on the way. Out of the 5 most common mobs to spawn(Zombies, spiders, skeletons, creepers, and witches) creepers and witches would have the lowest spawn rates; with realms, creepers spawn about as abundant as skeletons. Creepers also can spawn in groups ranging from 1 to 4, you would almost always see around 5-10 creepers in a single fighting night. At least, speaking from personal experience, on 3 different realms, creepers have always spawned more often than usual. I've noticed this problem occur back at version 1.14, that I remember.

 

On a separate, non realm world, creepers would spawn much lower; they would spawn individually, and almost full chunks apart. Finding 3 creepers spawn within 2 minutes on a superflat world, and spawning without buddy's, and with distance between them. In a not-realm world, creepers noticeably spawn less than on a realms

 

First image - This is on a realms that I am a part of, finding 4 creepers with 3 creepers spawning with eachother; the group of 3 creepers and the 4th creeper spawning only a minute apart, and during those 3 minutes of night, with these 4 creepers included, found 6 creepers.

Second image- This may be a superflat Creative world, but that doesn't affect creeper spawn rates, at least it doesnt look like it. I've found 3 creepers spawn what looks like a chunk apart, individually, and about 30 seconds from eachother. Only seeing about 4 within 3 minutes of night, not a big difference, but one that I enjoy better.

Haven't seen much people talk about this, but I hope it gets fixed.
