     - `sourceSystemName` - The source short system name of the game. For regular systems this value will be identical to `systemName` but for collections it will show the actual system that the game is located in instead of the collection system name.
     - `sourceSystemFullname` - The source full system name of the game. For regular systems this value will be identical to `systemFullname` but for collections it will show the actual system that the game is located in instead of the collection system name.
 * `defaultValue` - type: STRING
-    - This property makes it possible to override the default "unknown" text that is displayed if `metadata` has been set to `developer`, `publisher`, `genre` or `players` and there is no metadata available for the defined type. Any string can be used but you can't set it to a blank value. If you don't want to display anything when there is no metadata available, then set this property to `:space:` in which case a blankspace will be used. This property has no effect on the metadata editor where "unknown" will still be shown for blank values.

If you don't want to display anything when there is no metadata available, then set this property to `:space:` in which case a blankspace will be used. This property has no effect on the metadata editor where "unknown" will still be shown for blank values. A secondary use for this property is to set a default value if `metadata` has been set to `systemName`, `systemFullname`, `sourceSystemName` or `sourceSystemFullname` in which case the value will be used if the metadata value is blank. This is useful for defining a specific string at the root of the custom collections system.
 * `systemNameSuffix` - type: BOOLEAN
     - Whether to add the system name in square brackets after the game name when inside a collection system (automatic as well as custom collections). If `metadata` has been set to `description` then this property will only apply when inside the root of the grouped custom collections system where a summary of available games for the currently selected collection is displayed.
     - Default is `true`
