goodmorning

All weekend  have been trying to solve this problem:

on my mobile website www.dazzlingfashion.nl there is one item in the menu (tops) not shown. All other menu-items are working properly.

When I check it in X5 and go to the page tops/reponsive design the pictogram is not shown in the following:

720 PX viewport 2, 480 PX viewport 3, and smartphone.

What might be the solution to solve this problem.

Best regards
