screen size change resets object position

I have a "card" object parented to an other object with a grid layout group. I can change the position of the card normally, but when the screen get resized (either in editor or as applicaion), the card position resets to it's start position. When i removed the grid layout grop the position did not reset. Does anyone know how i can have a grid layout group that does't reset it's parented onejct's positions?
