Button position scaling weird

My game seems to scale perfectly with potrait resolution (tested on android phones).
But all my buttons are moving to the right.
What is causing this?


Canvas Scaler settings:

UI Scale Mode: “Scale With Screen Size
Reference Resolution: “X: 1080, Y 1920
Screen Match Mode: “Match Width or Height
Match: “0.5
Reference Pixels Per Unit: “100


The Button:

The Inspector:

hi;
its about your buttons not canvas scale setting;
look at the Rect Transform component of your button and check its Anchor;
it should be around the Button ;
