Hi Aulia,

It looks like the number of active batches in the problem wasn’t set or the number of inactive batches (`settings.inactive`) was the same as the total number of batches in the problem (`settings.batches`). Adjusting these attributes of the settings object so that `settings.batches > settings.inactive` should take care of that.

Best regards,
