I own Mordenkainen's Tome of Foes and have used legacy monsters from it in the encounter builder many times. For whatever reason, even though I can access the book, read it, and view it's content, the encounter builder will not let me view it's monsters. Upon further inspection, this is happening with multiple other books. Once again, I can still access the books and view their content, but in the encounter builder it is saying these monsters are not unlocked and I need to purchase the content again. When I do click the marketplace tab it brings me to whatever monsters stat block it's telling me I need to unlock.
