I think part of the space station's Remus and the other Romulus, with one older and abandoned and another more recent.
It's set between the first two movies, and is supposed to be a standalone, and probably intended for those who had never seen any of the Alien movies because they're too young, which is similar to what happened to not only Fury Road (made decades after the last Max movie) but even to Furiosa (made a decade after Fury Road came out), which looks like a Marvel movie set in a post-apocalyptic world. That might also explain why Romulus looks like an Evil Dead movie in space: it's probably intended as a reboot of the franchise.
The problem lies with those who are fans of the franchise, as there are glaring contradictions. For example, it looks like in Aliens no one had heard about the aliens, and yet in Romulus and in the game Isolation there are multiple personnel from many agencies (even corporations other than Weyland-Yutani) involved, and given the trailers, all types of experiments conducted long before the fourth movie, which is set more than two centuries after.
There are more complications given the prequels, and probably even more given the upcoming TV show.
