R03B525 RMDS not updating

Dear Team,

I need one help. While executing the reminders based on severity (R03B525 PO Notice Tab  # 6 =1), when I generate the notification, system is not updating the RMDS (No. of reminders sent) field.

Due to which I am facing below issues ---

1) when I execute the reminders on the same day multiple times system prints the notices

2) second notification is never called as system always treat this as first notification to customer.

Please find below the current setup:

Request you to please help to identify how to update the RMDS correctly.

Thanks,

SuryaD
