Redirection of some links not working

Hi! Usually the plugin works great and fast, but there are some pages, with identical permalinks, that do not redirect properly, they just go to the front page of the blog. If they hadn’t found the working links they should just go to the 404 page. Any thoughts on how to fix it?

Thank you!
