ARIA labels query in Sharepoint sites

Hi,

I have a question about Aria labels in SharePoint sites. When I carry out accessibility checks on a site created by another party, I notice that the aria label and aria described by attributes are being used 'incorrectly'. The description is being used in the label, and the label is being used in the description. Does anyone know how to edit aria labels etc in SharePoint? Is it possible as an editor, or are these handled by Microsoft?

Thanks so much for your help!
