Unable to load objects to level 2

[Prash]

Hey everyone, I am a beginner. I am trying to make a platformer game with 2 levels. I made the tilemaps using tiled and exported them to csv format. I used the csv files to load objects as well. The first level is working fine but the second level isn't. The second level is loaded and displayed but when I try to load the player or anything else, I get a black screen. I have attached the source code and the two maps.This is how I load the objects.

function addObjects():Void
    {
        coins = new FlxGroup();
        add(coins);
        enemies = new FlxGroup();
        add(enemies);
        var objectData:String = Assets.getText("assets/data/Oj_"+Reg.stage+".csv");
        var rows:Array<Dynamic> = objectData.split("\n");
        for (y in 0...rows.length) {
            var objectsString:Array<Dynamic> = rows[y].split(",");
            var objects:Array<Dynamic> = new Array();
            for (i in 0...objectsString.length) objects.push(Std.parseInt(objectsString[i]));
            for (x in 0...objects.length)
            {
                switch (objects[x])
                {
                    case 896 : addPlayer(x,y);
                    case 897 :addCoin(x,y);
                    case 898 :addDumbEnemy(x,y);
                    case 899 :addExit(x,y);
                    //case 900 :addFlyingEnemy(x,y);
                }
            }
        }
    }
