Item Images Disapeared from Description

Hello
I am using for some time now Catalog X and I like it a lot. But while I was doing some settings something happened and the images of the items in the catalog are not in their places in the description of the items. Here is the example:
https://spectronicbg.com/terminals/product-category/loading-and-unloading-arms/bottom-loading-arms-for-petroleum-products/
When I click on an subcategory item, there is no image in the description:
https://spectronicbg.com/terminals/catalog/loading-arm-sla-750lr/
I have selected a proper item image and I can see it in the edit item page.

Please help me.
Thanks,
Julian
