Try covering in waxed paper or plastic wrap and see if that makes a difference.
Some coverings are better than others.
Cheese has a water content and the covering prevents moisture release.

Some cheeses have a thick coating of wax or plastic for storage and preservation from the manufacturer.

Where are you storing your cheese?
