SQL false alert for simple recovery database model

Hello,

We are using Networker 19.4 and SQL server is 2012. Recently transaction log backup for SQL server database are showing up under Failed backup in under show details = Networker GUI though Backup and Clone as "GREEN TICK mark"

Recovery model of database kms is simple. Backup of database kms will be skipped.

I understand that Simple recovery database model backup are not supported by networker and as per Dell EMC documentation i can ignore by adding under client properties :

NSR_SKIP_SIMPLE_DB=TRUE

Not sure why it generates failure alerts in DPA report and comes under Failed backup list even under   NETWORKER GUI even though it is skipped. We never had this error message in last three months, Nothing changed from the  Networker configuration or SQL side.

Is there any reason why simple recovery database generates failed status under  networker ? Also under  NETWORKER GUI when we click any database to see its backup log but it says "No details available"

Please shed some light on the above
