How can you fix the thing where in FE kits the bullets show to the person shooting and not for others

So ive been trying for days to fix that problem but I cant fix it, module to module, script to script, its just hard to fix

The FE kit is not mine so i guess thats a problem because i dont understand anything of those scripts but if you have the time to help me fix the problem heres the kit: https://create.roblox.com/store/asset/17321501397/FE-kit
