Minecraft launcher Versions not loading

Minecraft Versions not showing up

What I expected to happen was...:
So im trying to set my version to Optifine 1.8.9 or Forge 1.12.2 etc. The launcher only accepts vanilla versions of Minecraft like 1.8.9, 1.12.2 1.14 etc. I click on "Installations" and click "New", goto "versions" and select "Optifine 1.8.9" or "Forge 1.12.2"

What actually happened was...:
The "optifine" and "forge" versions just disappear and wont come up in "installations". But the vanilla versions do.
