So I exported the GEDCOM from FH and used it to create a new tree in Ancestry which I wanted to make public. But when I started looking at it I have some sources that reveal the entire file path for the documents on my computer. I've obviously gone wrong somewhere. I have changed the tree to Private now until I can find out what I have done wrong and how to fix it.
This is what I am getting in some of the source boxes on Ancestry.
