Why is Splunk Connect for Syslog (SC4S) removing domain name?

We are migrating our syslog server to Splunk Connect 4 Syslog running on a RHEL server inside a Docker container. The syslog messages are being forwarded to Splunk, however, SC4S is stripping the domain name off of the device names, causing issues with interfaces that are sending log messages.

For example, the host - "hostname.contoso.com", will have the host= hostname, while the hostname 
"lo0.hostname.contoso.com.", will have the host = lo0.

It appears SC4S is doing some sort of split on the first period (.) in the hostname and only keeping the first item in the array.

Is it possible to tell SC4S to use the FQDN as the hostname?

We are using reverse DNS on the SC4S instance - ie. SC4S_USE_REVERSE_DNS=yes

Any help is much appreciated!!
