Pokemon Red Glitch issue

Hey, I recently bought a copy of Pokemon Red, and am having an issue with the Pokemon Storage System (Bill's PC) where pokemon placed inside glitch out. Their names show up with similar characters to the item multiplication glitch. If I interact with them, the game goes to white screen and crashes. I'm wondering what's causing this. Is my cartridge toast?

Edit: To be clear, the pokemon are not glitch pokemon going in. This is happening as soon as Pewter. The deposited pokemon are fine going in. I only referenced the duplication glitch to describe the pokemon name appearance.
