CTF template's intermission and Timer GUI are visible in studio but not online?

So i recently made a CTF game with the help of CTF template of roblox studio. into the game i added many scripts like map changing and Admin commands. for some reason after i updated the game and try to play it on online. the intermission doesnt take place and the GUI which displays the timer, score and all that isnt there. there is nothing wrong. as soon as i added my second map into the game. they all disappeared. they appear in studio but dont in online. by default the displaymanager script is a local one. my map changing script doesnt interfere with the other scripts either. though there is an intermission, the gui, the effect and the blur arent there.

this is my map changing script

and this is the displayscript, which works in studio but not online. this is a local script. this further contains TimerManager and Notification manager `
