Mobs from a few of the mods are not showing up on the first computer, they can attack me but i do not hear them nor see them

I have reinstalled java, installed a different version and set in launcher, updated drivers, cleared my minecraft folder and redownloaded all of the mods, tried the mods on the seconds computer( copied EVERYTHING in the folder including configs) and then noticed that it was able to see the mobs without issue.

What in the world is going on and how can i fix it?

OK, i fixed it by starting the mod pack in a server, something about the mobs not wanting to show to the host.

maybe it labled it as a server instead of a client and in the mod the server is not supposed to attemp to render the mobs.
