Draw calls and text on UGUI

Hey, I have a prefab that has a sprite and a text on it, when I duplicate it I get 2 draw calls for each duplicated prefab. When I duplicate without it the draw calls do not increase and in total there is only 1 (I used the sprite packer for the sprite used in this prefab). Question is, why do I get 2 draw calls per each prefab instead of only 1 for the text (the sprite is in a sprite packer so should take only one) and is there any way to solve this?
