Welcome, no that is not normal and not good, but it is a common problem.
Cause is because cheese is too moist and still expelling whey, not good as behind the wax it is a location for unwanted infections such as yeasts.
Agree, remove wax, air dry further then if want re-wax. If you go to the STANDARD METHODS - Aging Cheese Board then click on column title "Subject" it will sort all the threads in that Board alphabetically then click "Subject" again to sort from Z to A, then scroll down through the wax threads and you'll find discussions on Moisture Appearing Behind Wax and Fluid Leakage.
