Legacy information
The role
metadata, which provides an ARIA role, can only be declared once per quotation block and once per file outside of quotation blocks. However, your file declares it more than once in the same scope.

Declare the role
not more than once per file outside of quotation blocks and not more than once for every quotation block.
