Continuation on my Game Bug

I have made a report on this bug that affects which mobs I can see and what they look like, however it was marked as resolved. I believe I have found the issue with whatever is happening, and that is the Adidas Adventurers Add-On. I had activated it a couple of months ago and suddenly, whenever that specific Add-On was disabled, some mobs would be completely invisible, although still being there, some baby mobs such as the chicken would have the original model on instead of the revised yellow model for Tiny Takeover (when 1 Drop 2026 is enabled), and they would appear enlarged, larger than the adult model. Also, all creepers would appear charged rather than normal, even when not, however the animation was completely static/still. The images I’ve attached show what the game looks like with the Adidas Adventurers Add-On off (having an old creeper spawn egg model and strange creeper), and when it is on (creeper is normal and spawn egg is current), which you can see by the adidas guy in the left corner. This happens across my worlds as well, not just in one. I had turned on the add-on in another world and my creepers (which were weird) went back to normal, along with the chickens and spawn eggs (when in creative). I’d appreciate it if this issue was brought to your attention and fixed. Thanks!
