rsyslog duplicit configuration

I'm switched from Debian to Mint (Ubuntu based) with my workstation. I have a lot of remote syslog custom definitons files in /etc/rsyslog.d/, so I simply copy them into a linux mint, and check using "rsyslogd -N1", all was OK

Couple days later I found a serious amount of logs in my /var/log/syslog, which should be (and are) parsed and stored by my custom definitions, but then message processing should be stopped, and it is not for some reason.

After short investigation, I found an extra file /etc/rsyslog.d/50-default.conf with useless because DUPLICIT definitions compared to main /etc/rsyslog.conf file, and due its name is processed before my custom definitions and before DUPLICIT rsyslog.conf definitions. Stupid.

This extra file is NOT MENTIONED in package rsyslog anyway - see "dpkg -L rsyslog" output, and also "dpkg -S /etc/rsyslog.d/50-default.conf" shows to me : "dpkg-query: no path found matching pattern /etc/rsyslog.d/50-default.conf"

A bit unexpected behaviour IMHO

Normally, rsyslog.d/*.conf custom definition are parsed before rest of default definitions at the end of rsyslog.conf, but this file change the rule order (to make them duplicit by some unknown reason)

So, I suggest You to repair package descriptions to mention this file existence, better to remove this useless 50-default.conf, or at least mention his existence somewhere in rsyslog.conf before conf.d/*.conf file inclusion, or maybe rename this file to zzz-useless-duplicit-default.conf to guarantee right order.

Could You, please, spare user's time and frustration from this strange and odd Ubuntu specific rsyslog behaviour ?
Debian and Redhat distributions not crippling rsyslog confioguration that way.
