I have no idea what’s up with that, but maybe @nick could help.
Now I think I know why. There must be a level in development that you can’t see yet, so they already changed one thing but not the other. Or it could just be a mistake.

HoC2016
HoC2016 is for the Hour of Code and won’t normally show up, but I wonder if it’s causing an off-by-one error in the counts here.
You don’t appear to have Cupboards of Kithgard B, because you probably did A fast enough that it decided you didn’t need extra practice on that concept. You aren’t missing much. 
Sleeping on the Job is answer 
sorry for countinuing this old conversation but i have 53 and i did hoc2016
Some levels in Kithgard are unlocked later on. For example, I believe a level unlocks once you have beaten a certain level in Forest and another one in Desert. Have you completed those worlds?
Yes I have 130/130 in backwoods and 87/89 in sarven
Yes I have 130/130 in backwoods and 87/89 in sarven
Send your username to team@codecombat.com and I’ll tell you which level is missing. It may be that it’s one that unlocks from somewhere else.
shall I private message you
That works too – but I generally read our support inboxes first.
For Desert, you’re only missing one level, a subscriber only level named Golden Mirage (plus the two levels you have not completed). You have all Dungeon and Forest levels compete.
