Mobile View not working properly

Website was working fine last night but next morning (today) when I changed the hero image on the projects page it shows exactly the same settings of the position in the x and y direction on mobile view in the desktop but when I checked it on the real mobile phone the settings were not the same that I set previously then I did some settings of the mobile menu it shoes the same problem that in the real mobile phone the changes are not propagated.
