Error · duplicate-id-aria
Repeated internal names in labels
Lighthouse / axe call it: IDs used in ARIA and labels must be unique · ARIA IDs are not unique
A label points to a name used twice, so it may describe the wrong element.
Who it leaves out: blind people (screen readers)
How to fix it
Make the name unique. Developer task.
In the code
Make the id referenced by aria-labelledby / aria-describedby unique on the page.
