Easy Experience not working

I have been using Easy Experience successfully for a while now and really like it however, in one of my campaigns it has stopped working.  When I select !XP -session (award experience ) it crashes my API sandbox. In the sandbox the error shows up as: "adding xp" Error: Firebase.update failed: First argument contains NaN in property 'current' Error: Firebase.update failed: First argument contains NaN in property 'current'     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 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:908:27)     at Timeout.later [as _onTimeout] (/home/node/d20-api-server/node_modules/underscore/underscore-node-f.cjs:1146:37)     at listOnTimeout (internal/timers.js:554:17)     at processTimers (internal/timers.js:497:7) "Loading character sheet data..." I am using 5e OGL. I have tried removing all other scripts, removing and replacing the EasyExpierence ver 1.13, removing and letting the XP - config regenerate the ExperienceThresholds sheet. I have made a copy of the game and it works in the copy. Please help!

I notice that the ExperienceThresholds token that is auto generated when the script is first configured has a lot of extra Attributes in it such as hitdieroll and showleveler. It doesn't have these fields/Attributes in the games that work.
