Impossible to remove store image or any image (icon not displayed) in VM3

[overseas]

Hello,

on my virtuemart administration, I haven't the icon to remove image (small red x on the top right of image like in VM2).

However, i have the tag <span with vmicon-16-remove but remove icon is not displayed.

My joomla : 3.4.8
My virtuemart : 3.0.12
My admin template : Isis

Do you have an idea or a solution?
