I have not looked into this particular case, but it is entirely possible that the profiles have been created. The problem is that red is used to indicate a link error, meaning that there is a link but it is to a page that does not exist.
The link is supposed to be formed in the format:
[[LNAB-#|Link Text]]
The "LNAB-#" is the WikiTree ID of the person and the "Link Text" is what appears as the link on the view page. The link code starts with double left bracket and has a pipe character between the WikiTree ID and the link text. For example, if you put:
[[Stokes-3595|Marian Hearn]]
on an edit page, your name will be displayed on the view page and will be a link to your profile.
The links in that profile were not correctly formatted - they only had the person's name - so they would show as red and lead to an error page if you click them just because of that, whether or not a profile exists for that person.
Both previous answers are correct for how to fix the problem by simply removing the brackets that create the link.
