My custom modpack is launching vanilla minecraft instead of the mods.

Like in the title, my custom modpack is launching vanilla minecraft instead of the mods. I have tried to fix this on many other forms, and no dice. 
Thanks For Your Help In Advance!

Let me know if you need me to attach anything else! Thanks!

Your bin folder contains both the Forge 2854 universal and it again but renamed to modpack.jar. However, due to internal changes to Forge, you need to use the INSTALLER renamed to modpack,jar for Forge 2851+. Do not extract it, use it just like you would use the universal.

Edit: Also, your modpack seems to be a mix of 1.10.2, 1.12.2, 1.14.4 and 1.15.2 mods. You can only use mods for the version of Minecraft + Forge you included.

Additional Edit: I also spotted a mod for 1.7.10 and 1.8.9.

Not a launcher issue. Moved to Platform Pagoda.
