And aside from explaining why no one from a new show references past teams there's no real problem here is there? You're just taking the position that they're all separate because you want to, but they don't have to be. Nothing explicitly says they can't be, and the movies are totally cannon with their shows. This isn't Kamen Rider where half the movies don't work.

Even in the Gaoranger movie they had a massive team up to establish a shared continuity, albeit a loose one. Previous heroes of various colors from many generations teaming up with the current ones, even explaining the history of how sentai in the past have triumphed to their successors. One show has a crossover with the previous one, which then has a crossover with the next, then that one with the next, all of them are connected via those crossovers. There's no reason why they can't be.
