automatic switching product image problem

[Noorya]

Hello

I need help, 

when I log in to my store using a laptop if I tried to select one color for example for a product from a variety it does not display what color I chose. On other hand, IF I log in to my store from mobile once i select any option or color display what I select.

I use  Express theme
