MP - empty cell in import CSV file

The PB supports import with CSV file.
However, when one of the cells of the file is empty ("" or " ") the task is not created and the system gives a 500 error.
The workaround at the moment is to edit the CSV and put a character in all empty spaces (ie. "-")

I would like the system to be able to handle empty cells properly, ie. treat the empty cell as missing info (not displayed).
