Hyundai Santa Fe sport 2016, AWD, 5 seats, gas tank leak when full tank

What is your question?

When I make the gas tank full, I feel gas smell in my car then I checked I felt little wet under the gas tank so there is some leak but not always it happens when I make the gas to full tank. If I stop filling gas to auto stop then I didn’t feel any leak or smell so please advise . Why it’s leaking when it become full tank may be there is any vent or any other issue
