Hello Michael,

To add the tags manually please follow this advice from the help file:

If the H1 and H2 tags cannot be handled automatically, and if you want to handle subsequent heading tag levels (remember that there are 7 levels, from H1 to H7), you can do it manually. Insert the titles using the Text Object or HTML Code Object options.

If you use the Text Object option, you can use the Enable HTML Code command to add the code and include the title in the tags: for example, type <h1>Title</h1>.

The same procedure applies if you use the HTML Code Object option: however, in this case you cannot use the text formatting features available in the editor.
