Duplicate element id
What it means
The same id appears more than once on these pages. Every aria-labelledby, aria-describedby and <label for> pointing at it resolves to the first one only, so some controls quietly get the wrong name or none.
How to fix it
Make each id unique. Duplicates almost always come from a component rendered several times with a hard coded id. Generate one per instance instead. WCAG 4.1.1.
