What is saying its a well-Formed error? Preview? Epubcheck?

Make your change as above and then Perform a Well-Formed check using the Sigil menu item. Let's see what the actual error message says as a I can not see an error.

If only Preview shows the error then I am guessing your Nav is missing the required epub namespace.

Is it missing the attribute xmlns:epub="http://www.idpf.org/2007/ops" attribute on its html tag?

If so what generated this Nav? Where is it from?

Another thing to try is to run Mend on your nav but that may not help if you have not defined the epub prefix needed for epub:type.

Insert a blank xhtml using BookBrowser under epub 3 and look at the "html" tag it generates.
