How can I fix this team changing bug in my round based game?

Hello, me and 2 others are working on a new game! It is an obby based game inwhich 2-10 players will get teleported to an obby, the last to complete the obby/furthest away from winpad when the timer runs out will get eliminated, this will continue until there is 1 person left they will get a win, (and if you complete a map you get 25 coins). However there is an error, sometimes the player will not switch from lobby to obby team (and vice versa) meaning sometimes you wont go in when a new game starts and sometimes noone will get eliminated after a round. we are noob scripters so any help would help thanks! here is the full round system script, if you notice any bugs please say!
