Bug Canvas world space

I have a canvas on world space on a VR app for android devices, when I run the app on editor everything is correctly placed and all the inputs work. When I build the app the buttons "onClick" move to the left, the button that worked when pressed on the middle in the editor now only works when pressed to the left of the button on the build even tho the UI itself still shows to be in the correct position when looking at it. Does someone know how to fix it? I have the archors set to the corners where those buttons are suppost to be already
