individualCount=0 while occurrenceStatus=present, not picked up

When making a QC on this dataset: http://ipt.medobis.eu/archive.do?r=dori it has been noticed that an issue is not picked up by the tool. The issue is the fact that one occurrence has individualCount=0 while occurrenceStatus=present which doesn't make sense.
Need to be investigated if it's a bug or if the tool is lacking a check for those type of issues.
