Ammo tracking error - 5th Edition OGL by Roll20 Companion.

So when I try and use the ammotracking this error keeps coming up and stops it from working, I've just started using these scripts so not really sure what it means, any help would be appreciated.   Error: Firebase.update failed: First argument contains NaN in property 'current' Error: Firebase.update failed: First argument contains NaN in property 'current' at Error (native) at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:9:186) at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:207) at Aa (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:8:462) at Ea (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:403) at H.J.update (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:146:318) at TrackedObj._doSave (/home/node/d20-api-server/api.js:566:27) at later [as _onTimeout] (/home/node/d20-api-server/node_modules/underscore/underscore.js:828:25) at Timer.listOnTimeout (timers.js:92:15)
