How to empty 2nd black water tank on 2017 5er

I have a 2017 Montana 37 ft 5th wheel. It has 2 Gray water tanks with 2 pull handles and 2 black water tanks but I can only find1 black water pull handle. The indicators on the panel shows 1 full and 1 empty. How do I empty the second tank? It has only 1 hose connection on the outside to connect a sewer hose to.
