Texture Quality change causes UI to dissapear

I have a drop-down menu that changes the Texture Quality (High, Medium, Low). The default is high but if I change it in the game to Medium or Low random parts of the UI disappear, yet are still interactive like the drop down or the back button. Is there any way to fix this.

I figured out the problem. I did set any UI with the Image component to Raw Image, and when I compared the regular UI Toggle to the one with raw images, I saw that the Toggle component did not have the checkmark sprite as a graphic image. I set it up and now it works.
