Saving a job after importing items from a csv file throws an exception and crashes MaxCut

Hi,

When I import items from a csv file and then try and save my job file I get the following error and MaxCut crashes without saving the job...

De objektverwijzing is niet op een exemplaar van een object ingesteld.

English translation:

The object reference is not set to an instance of an object.

Adding items to a new job manually and then saving them works fine. Please could you help?
