The real problem here is that the mother https://www.wikitree.com/wiki/Stewart-1854
is PPP but there is no project listed on the profile. It should probably be the Scotland Project, but it could be Euroaristo. One of these projects should take over so that the spurious child can then be detached.
The father has already been detached and the Gordon profile orphaned by the previous manager to facilitate this.
Instead of pounding on the keyboard, the project tags should be added to the question to draw their attention to the issue.
