Also, the two group by and view options at the top of the page isn't working in my testbed page layout, although it is in the basic link page. Is there a way to make that work? https://wwwext.arlut.utexas.edu/testbed/faculty5/publications/#

This is a known issue for some people. There is probably a conflict between some of the libraries bibbase uses and the ones you are already using on your page. It's best in those cases to just hide those dropdowns using CSS:

#bibbase_header {
     display: none;
}
