assigning images in dark mode not formatting

Hi

does anyone else have the experience in AJO where you assign a different image for dark mode, but the formatiing is completely off and connot be adjusted?

My image in light mode is fine, but when I add the dark mode image it left alignes and no matter what i do i cannot center align it? in fact the settings under dark mode affect the light mode images. Anybody worked successfully with this ?
