Why are only the first images draggable in my section?

right now only the first image is draggable somehow, the rest in the section don’t work despite having the ID tag on them.

{%- liquid
  assign slider_is_enabled = false
  if section.settings.mobile_layout == 'slider' and section.blocks.size > 1
    assign slider_is_enabled = true
  endif
