Current Forge not working for mods?

[Yemoja]

I tried to download these mods here:

 

https://www.curseforge.com/minecraft/mc-mods/jurassicraft

https://www.curseforge.com/minecraft/mc-mods/llibrary

And everything seemed to be running smoothly, that is until I was confronted with my game stating:

 

'File Jurassicraft-1.12.2-2.1.23.jar is for an older version of Forge and can not be loaded' 

As well as the same line, but with LLibrary

So, I tried to download bunches of different versions of Forge, from the most recent to recommended, 1.12. and 1.11, and still nothing. Am I doing something wrong here?
