Custom mod, UI won't show up

I tried to make a mod for the server so me and my friend could have more fun in, but the mod won’t show up the UI to add it, and i don’t understand why, I did researches and tried many things, it will not show up in the UI Add tab.

Current client side (server works just fine)

SeekRun/lua/ge/extensions/Seekrun_client.lua
SeekRun/scripts/SeekRun/modScript
SeekRun/ui/modules/apps/SeekRunHUD/app.css
SeekRun/ui/modules/apps/SeekRunHUD/app.json
SeekRun/ui/modules/apps/SeekRunHUD/app.js
SeekRun/ui/modules/apps/SeekRunHUD/app.html
SeekRun/ui/modules/apps/SeekRunHUD/app.png

(SCRIPTS WILL BE PROVIDED IF ASKED FOR)

EVERYTHING BEEN FIXED (Edited)
