It is possible that the message you are getting is due to a bug of some sort. However, it may be something you can fix yourself.
If you are finished with adding profiles from your Gedcom, you should be able to delete the Gedcom using a link on the page for it (look under the GEDCOM page found under your MyWikiTree tab). You have marked all but one of the entries in the GEDCOM as complete, which suggests that you have added everyone you intend to add.
If there are unknown/unidentifiable profiles in your Gedcom, there is no good reason to try to process them. (if you cannot identify them, they do not belong in your family tree.)
If you cannot resolve the problem by deleting the GEDCOM, do try contacting firstname.lastname@example.org about a possible bug.
