A problem with downloading books of a certain level

Hello! I’m selecting A2-level books from the catalogs (for example, “Poirot Investigates” or “The Secret Adversary”), but when I download them to the library, they are automatically downloaded as B2-level originals (700k and 430k characters). I’ve cleared the cache, and I’m using the latest version of the app. This is most likely happening with more than just A2-level books. Please correct the level files on the server.
