The current practice is due to Young Peter Hale being two distinct characters - Lydia's Hallucination and the actual person. As other characters were given younger versions, they were added in a similar manner.

As to it being confusing - it's actually been a help with SEO since a large number of people search for more information about the character's younger selves.
