Yvonne Adele Janus is John King the father of any of Lucy Miller's children?
What we should have is Lucy with two partners, one John the other Unknown and then assign the children to which ever father is appropriate. If at some point the identity of Unknown is discovered it is simple to edit the profile.
If you would like assistance with setting up I'm happy to help.
The fact that John is listed as father on Reuben's baptism record suggests that he is actually Reuben's father so I am not sure why you have placed "stepfather" in John's name field, it's surely not his name?
I've taken the liberty of removing "stepfather". If John is not the biological father of Reuben's siblings then we can handle that as per my previous comment.
