Mods not working on a Forge server

[Gumpy]

Hi, I've made a Minecraft server with mods but there're two mods (Primitive mobs and Flans mod) that appear on the creative inventory but there isn't anything. I don't know if the mods aren't compatible with other mods. The Minceraft Forge version I'm using is 1.12.2-14.23.5.2847

 

Im using the floowing mods:
