Undesirable images size and view in brandstore Astra theme store page in mobile

my store page in mobile version is not showing correct format of images like showing 2 product images at one time instead of one and also other content is not good. I’m not able to find the reason behind this. If I see that page mobile versions in desktop they are good but I practically open it in mobile they show error. Thanks in advance for support.
