When adding SRV records, the overview / list of all records only shows the _service._proto part, but not the actual name - e.g. it shows _minecraft._tcp instead of _minecraft._tcp.subdomain.
As seen in my screenshot, I have added an SRV record for _minecraft._tcp.mc.mydomain.com, yet it only shows up as _minecraft._tcp.mydomain.com in the list, ignoring the “mc” name of that entry.
This is by the way just a visual bug - the actual record does work fine.
