I'm trying to download a texture pack I've just purchased however I keep getting an error message stating there is not enough space. 

However I have enough space on my PS4 and on the minecraft internal storage. I've deleted old worlds, deleted old resource packs, deleted duplicated saved data. My world is only 366.2mb and has not used even a quarter of the storage. I'm unsure what else to do? Any information would be greatly appreciated.
