No problem

It's not that the Ranger is able to overlap that is the problem. The right background in tabletop also gives access to the thief role for Rangers (and anyone else). It's that they made it so that Rangers have more skills, more additional features like PFEG and Find Familiar, and made Guidance omnipresent together that just pushes the Rogue right to the side, because the only measurement on skill checks that matter is "good enough". The Ranger didn't need all these features at lvl 1. What the Ranger needs is better scaling from lvl 6 onwards. And BA Hide needs to be Rogue exclusive.
Fair I guess, though this might be better explored on a thread about issues of originality, balance, flavor, and function that rogues face generally. I'm not sure how the topic of rangers pushing rogues to the side came up, but I don't know how relevant that is to what I'm trying to say.
Which is that in the current implementation of favored enemy, with the exception of ranger knight and bounty hunter(because they introduce meaningful passives that alter general style of play), are underwhelming in both flavor and function. If they are going to have a favored enemy feature, I would like it to more meaningfully change the rangers kit to provide some mechanical uniqueness to each option. The minor buffs in different skill proficiency don't actually do a ton to add to character flavor or function where as I think changing how certain abilities function depending on favored enemy or what spells can be accessed during character progression would add more depth to each favored enemy option and therefore to the ranger class as a whole.
