You are setting player variable for job cp (GunoierJob). Why not make new variable and set it for air drop?

pawn Код:

public OnPlayerEnterCheckpoint(playerid)
{
    if(Airdrop[playerid] == 1)
    {
        // Airdrop code here
        Airdrop[playerid] = 0;
        return 1;
    }
    if(GunoierJob[playerid] == 1)
    {
        DisablePlayerCheckpoint(playerid); 
        ...
