Sprites appear and so go to the right position

Hi,
I have a little problem: I insert some sprites on a container but the sprites only go to the right position after one game loop update. For exemple, sprites appears outside of the right position for just one frame and so after this the sprites appears on the right position relatives to the container.

What should I do to evitate the “jump” of the sprites inside the container?

Remake, how can I update the container before the game loop update?

Your code?

Man, I perceived that the bug is random, should be something wrong in my code. I don’t have permission to expose the code, so, I will review the entire code until gets where is wrong.

@samme solved, thanks and sorry for the inconvenience.
