Location of object changes with maximize on play

Hello,
I have a question regarding the location of an object changes with maximize on play. So what happens is when I do not maximize on play the object stays where it should however when I maximize on play the object moves to a completely different place. I will post video of what is happening in the link below since it is hard to explain. The only possible thing that I could think of was maybe it has something to do with Scale with Screen Size however I am not sure. Any Help would be greatly appreciated. Thanks in advance.

You need select the ‘Canvas’ GameObject, then the component ‘Canvas Scaler’ change the ‘Constant Pixel Size’ with ‘Scale With Screen Size’.
