Note: this instance contains much data, and has been loaded via several CSV files at the same time, one file per year (that may be the reason why it did not happen on any other instance yet).
The query for the data, in this case do not use any ordering (due to this condition, saying only that any chart type different from histogram should order data on counting value).
One has to add an else block to order on the _id field (asc, and not desc), see these lines in dashboard.js)
