It sounds as though the initial drying was too quick, so the outside dried out, but the interior was still damp. Have you actually waxed it yet? Best to wait until it seems dry before either waxing or bandaging. I'd suggest leaving it in your cave which seems to have good temperature and humidity, if you have it in a closed box wipe the moisture out every day and maybe crack the lid open a bit. When the surface seems dry again then you can wax. If you don't the moisture will gather under the wax and the cheese won't taste good at all.
