Your first citation appears to have been split in two, M. You may have extraneous spaces or line breaks, which should be removed. You also have an extraneous letter at the end of your surname in that citation.
And if you want to create links for the WikiTree IDs, you need to enclose them in double brackets instead of single brackets (you would need to update your name to your WikiTree ID to create a link for it).
Other than those minor points, MT's profile is shaping up nicely!
