please give information on the data you use, what processing you appled and at which step the error occurs.
The error message alone does not fully explain where the error could come from.
if it only happens for one product, I suggest reprocessing it from scratch. Could be that data was somehow lost during the subsetting. Its always good to select File > Save Product after you have modified your data so that the changes are physically written and will be transported into the next processing steps.
