Hi Emmanuel,
Thank you very much for the proper details, I think I know what you are looking for. By default, in some layouts the magnifier position is set to the right, but it can be changed on the back-end here: https://i.imgur.com/p6Q8lBg.png
Since you added temporary back-end details, I have made this change for you. If you clear your page cache and browser cache, you should be seeing the magnifier icon on the left side now, as you expect it.
