Yes, we're also getting way too easy books home. (And then reading harder books when DS wants to)

My parents had the same problem in school, and they fortunately just ignored the books from the teacher and let me read whatever I wanted. They also didn't insist I read out loud too much (which I didn't like because it was too slow).

Maybe read the proper books once a week? Or less? But don't condemn your child to books they hare.
