Missing Characters.

I haven't played on Suramar for a long, long time. I noticed today when I logged on there that I was missing two characters. Krondis and Fyreye. Even though i know I haven't deleted them. On the realm select screen it says I have 7 characters there, but only 5 are on the character selection screen. If I create a new character with one of those names, it's unavailable. So I know they are there, just invisible.
