Parmesan Reggiano is leaking oil?

Hi I️ figured someone here might know what might be going in more than the regular cheese subreddit.

I️ bought a piece of parmesan reggiano wrapped in cling film. Over the week or two I️ left it out it seems to have released clear oil that since its osmosing through the film smells like parm. So far there is no mold or signs of spoilage.

Just wanted to know if that’s normal? and what might be a better way to store it?
