I install some mods, some of them work, but others don't

The mods appear on the creative mode, and I can place them on my bar, but I can't place them on the map they instantly dissapear. I have installed the mod of animations and it works, but the others won't, I have them install on the Nitrado Server, and on my client, the mods and server are in version 1.12.2

What about the logs?

How can I activate those mods that are white/gray
