Help with Proctor Teagan's "Feeding the Troops"

So I have been playing the "Feeding the Troops" given to you by Proctor Teagan on the Prydwyn over and over aigan, since it's a pretty decent income of caps.



However when I approached Teagan today, there was no option for "Extra work", so is this a bug or isn't "Feeding the Troops" a repetable quest from the beginning or what's going on??
