Sending to Remote Syslog fails When Multiple Topics Are Selected

Hex Gr3 (The new one) and a hAP AC Lite both on 6.38.5

I’m able to add a remote logging action, over IPv6, and it works wonderfully when I add a single enabled entry with the topics of info, warning, error, critical.

/system logging add action=syslog1v6 disabled=no topics=info,warning,error,critical

If I add a second logging entry the logging server, confirmed via tcpdump, stops receiving syslog messages from Router OS.

/system logging add action=syslog1v6 disabled=no topics=ipsec,debug,!packet

Also, if I run with only 1 remote logging to the defined action but the topics of “ipsec,info,warning,error,critical” it also stops sending syslog messages from Router OS. Again confirmed by tcpdump on the syslog servers.

Am I just not understanding how the topics work? Also, is it normal to be only able to set a single /system logging line to a remote action.
