i don’t have an exact solution, but since i also don’t want your problem to remain totally unsolved (after 2 weeks), perhaps this workaround might help you a bit.
obsidian can detect “unlinked mentions” based on alias as long as it is not already a link – meaning it will detect [email protected] but not [[[email protected]]]. you can remove the double square brackets, and when you go to ur Person/Company file, you’ll see the potential links under “Unlinked mentions”
i you have too many of these links created already and feel a hassle to do global search in obsidian, you may refer to the post below for bulk search and replace using vscode or atom.
also, to avoid creating “duplicate” links like this in the future without realising it, i highly suggest using various complements plugin and enable “Internal link complement”
