FG-101F on A-A, the backup configuration is storing 2 files

I have recently upgraded to FG-101F (A-A v7.2.4) from FG-300D (A-A v6.4.11). Until using FG-300D, the daily backup script on the firewall sends the configuration to my FTP server as 1 file (FG-300D_Daily.conf) which will automatically be renamed by the FTP server with the timestamp as (FG-300D_09-Apr-2023.conf). After migrating to FG-101F, the backup is sent to my FTP as 2 files with the device serial numbers as FGT101F12345_Daily.conf & FGT101F67890_Daily.conf. The numbers that you see are the 2 device serial numbers of the firewalls that are in HA (A-A). Not sure if I am missing something here. Can you assist me on this so that it just sends one file as how I use to receive while using FG-300D?
