syslogd2 settings wiped after synchronization

Hi all, hope someone could help, we forward logs to ForitSEIM and configure syslogd2 also to send logs to Splunk collectors. I noticed when we make policy changes to Traffic VDOM config and then push it out to all FGTs, the syslogd2 server setting get wiped out on all firewalls. We have 11 FGTs and each is configured to use SPLUNK collector’s IP located at firewall’s location, so I have to manually configure syslogd2 on each firewall all over again. Thanks
