Customizer editor moved to the right, how to revert it back to the left?

[ShopOwners]

I have no idea how it got there, is there any way to place it back to the left?

Are you referring to the standard functionality of when the browser width exceeds a certain point, the customizer options appear on the right? if so, you could reduce the width of your browser to snap it back to the left.
