What it does

Reports a component whose meta.name equals the name of an earlier sibling (a component with the same parent).

Why is this bad?

Perspective addresses components by name: getChild('Label'), getSibling('Label'), {../Label.props.text} and /root/Panel/Label all resolve to the first sibling with that name, so the second component can never be reached and bindings silently read the wrong one. The Designer normally prevents duplicates; they appear after hand edits, merges or copy-paste between views.

Example

"children": [
  {"type": "ia.display.label", "meta": {"name": "Label"}},
  {"type": "ia.display.label", "meta": {"name": "Label"}}
]

Use instead:

"children": [
  {"type": "ia.display.label", "meta": {"name": "Title"}},
  {"type": "ia.display.label", "meta": {"name": "Subtitle"}}
]
