Invisible image

Hi, I have a problem with a custom image field. I have recreated all custom field from ACF. Everything works well except two fields with an image. I use Oxygen Builder and at the bottom, I have a Repeater section with an image and added field with the image but I see only a broken link. It doesn't matter that is a .svg image or .png image. If I add a new field also the image is invisible

You can check it at the bottom of this page:
