Deleted DLC, one Account still acesses

I deleted all DLC and basically restarted Halo 4 from scratch… however, one of the accounts that previously was able to access the DLC can still access it even though it was completley deleted.

Also, it erased my rank and took me all the way back to SR-1, not sure why it did this there was no corrupt files. Can someone please help me?

Deleting your files won’t reset your rank to my knowledge, something else must be going on there.
