I guess my prefab Spawning is limited when I Build Project, how do I remove that?

Hey guys, I`m creating my first game and when I run it in Unity its perfect, all the prefabs are spawning randomly on the scene, its limit is 30 since I made it to spawn until the number of objects is lower than 30. But when I build the game and run it out of Unity there are always, 5 or less objects in my scene, is there something on building configs limiting my number of objects?

Thanks
