The 6x version of the Capstones theme does not include a link for the Client/sponsor field: https://oaktrust.library.tamu.edu/handle/1969.1/188695

For acceptance, the 7x version of the theme needs to have the anchor tag removed, preferably by utilizing a different, existing dspace angular provided component.

dc.contributor.sponsor falls under ValueListBrowseDefinition within dc.contributor.* causing the generic item page field to render as a browser definition link.

This is determined by asynchronous request https://api-dev.library.tamu.edu/dspace7/api/discover/browses/search/byFields?fields=dc.contributor.author,dc.creator
