Thanks for reporting this. We will review and follow up.
Provider host name is always translated to IP address by purpose so you will not see it anywhere in the product. You can create feature request if you want to see the host name instead. Anyway the host name is stored in db and the translation to IP is done periodically using the hostname so you don't have to edit the IP on environment running on DHCP.
Provider name should be changeable and this is a bug. It is fixed in the next release of SRM.
