It doesn’t. Galaxies studied were very far from Milky Way and hence much older. This discovery shows that era of massive stars ended later in evolution of universe than we’ve assumed, not that we got mass of stars wrong.

We still see younger galaxies with less massive stars not rotating as expected.

You mean younger, right?

Weird English quirk when you have relativistic distances: They are older in a sense that they aren't recent. They aren't older in a sense that they've existed for a longer time. (At least in the radiation we're seeing.)

Like looking at an old photograph of a child. Both older and younger at the same time.
