strsplit()'s first argument must be 1 character long. If it is longer than 1 character, then ANY of the characters are treated as a delimiter. In your example

local realm, name = strsplit(" - ", UIDropDownMenu_GetText(CFM_LoadBox))

The delimeter you provided is basically " " or "-" (with " " repeated). So if you're splitting "Blackwing Lair - Chaosinc", then you end up getting the following returns:

"Blackwing", "Lair", "", "", "Chaosinc"

There are 2 empty strings there because there is nothing between " " and "-", and the second one is between "-" and " ".

If you are splitting "Barthilas - Xinhuan" then you basically get

"Barthilas", "", "", "Xinhuan"

Hence in your example code, your realm is correct, but your name is an empty string.

What you really want is this

local realm, name = string.match("Blackwing Lair - Chaosinc", "(.+) %- (.+)")
