Thanks for catching that, I fixed it here by making the background black like the rest of the row: https://github.com/pfsense/pfsense/commit/17694a106773ece2cdfb967255f92e3b627f01f9
As a side-issue on that screen shot, do a ctrl-F5 (or whatever key-combination it is on your OS/browser) to force a reload of all the JavaScript and CSS. That will make the "*Hostname" "*Domain" go away and turn into Hostname Domain
After an upgrade, everyone should do a browser refresh - because old JavaScript and CSS can get cached for a while in the browser.
upgraded hardware due to c2000 restored config and this now works so guess somethin in my dhcp6 leases file had a problem maybe just delete file and see if it fixes problem
