OnBefore Transform Script's log.info(str) Not Working

[JosephW1]

Hello, does anyone know what causes the symptom shown in this script to occur? Thanks!

EDIT: See the Import sets properties [ServiceNow Docs] page for more info on Import Set properties, as there is no "Import Set Properties" module in the platform. Thanks @János! 

onBefore Transform Script

(function runTransformScript(source, map, log, target /*undefined onStart*/ ) {
	log.info(source.sys_import_row + ' info'); //does not get created
	log.warn(source.sys_import_row + ' warn'); //gets created successfully
	log.error(source.sys_import_row + ' error'); //gets created successfully
})(source, map, log, target);

Transform History Form

Here are the results when ran on an import set that has 3 import rows. You can see that both A) the transform script ran because the warn and error lines are present and B) the log.info(str) did not work properly because the info lines are missing.

Any ideas? Thanks!
BTW: This is on a fresh PDI and using a global table, transform map, and transform script.

Thank you! Anyone know if that's a new property in San Diego or Tokyo? I don't remember needing to enable it in the past.
