Unable to Add Servers To Friends List - Win 10

I opened Minecraft Windows 10 Edition Beta, Click PLAY.
I press friends and then "add server"
I fill in a Name, (lifeboat) IP, (mc.lbsg.net) something like that and Port (19132)
It is an 0.12.0 Server. I press add server, and NOTHING is in the friend's list!
I expected it to appear in the list.
