need help spawning in missing mod mob in modded biome

[tomtom27373-alt]

Hi, I'm trying to create an ultimate adventure/survival single player world for my Minecraft game on version 1.20.1. The version includes mods like Alex's mobs which adds new mobs and the Outer Ends mod which expands the End dimension with new biomes and it's own mobs, When I go to the Azura forest biome from the Outer Ends mod there is supposed to be some mobs called Spectriflies flying around but when I get to that biome none are spawning in no matter how long I wait, I believe this could be an interference from Alex's mobs flying mobs in the end such as the Spectre or a school of Space Cod.

I have downloaded the In Control mod to try and stop Alex's mobs from spawning in the Outer Ends biomes so that it's mobs can spawn in but I don't know how to work it out.

Could anyone help me pls?

Cheers!
