Why does my Saved Host List not always save Aliases? (I think this issue is back)

I have noticed I'm no longer able to save the "Alias" in the List of Computers on the right, It only accepts the Hostname or IP on "Saved Host List". Please look into correcting this as we use the alias to keep track of our users and the systems they are using, thanks
