Authors not showing correctly!

Hey guys 2 friends of mine decided to become authors in my website, but now I have a small problem… Say if I make a new post and publish it, the author of that post it’s not me even thought I maded, it shows either one of the 2 new authors, I know at the very bottom when adding a new post there’s an option to select who the author is, well it only shows my 2 friends and not me even though I’m the admin, it’s getting a bit anoying 🙁

Any way to fix this? Any suggestions are welcome!

Thanks in advance.
