How to Leave Security Level, Components, Fix Versions or Affects Versions Blank When a Default Value Is Specified

Question: How do I leave Security Level, Components, Fix Versions or Affects Versions blank when a default value is specified?

Answer: When an issue is created or synchronised and the mapped field in MS Project is blank, the JIRA field is set to the default value specified in the mappings.

To make the JIRA field empty regardless of the default settings, enter '(none)' in the respective column in MS Project.
