Why won't my header show in MS Word using OOXML & Word JS API - ms-word

Question

Trying to use Visual Studio 2017 to do this: Why is the header not showing in MS WORD? I tried to simplified from a real dotx document that was saved as XML. I managed to make it work with plain body text and even floating images in the body. But before I could work on images in header/footer, I am trying to test it with plain text in the header, but I just can't seem to figure out how to make it work. Thank you!
