IDs used in ARIA and labels must be unique
What is the problem?

Impacted Groups
Why is this important?
Screen readers and other assistive technologies rely on unique id attributes to identify and label elements. Duplicate id values can confuse these technologies, leading to incorrect information being conveyed to users or preventing them from accessing certain content.
How to solve this issue
To fix this issue, make sure each id attribute value on the page is unique.
