I didn't get why her name was not on the main credits during that season...she was in a lot of episodes, almost the same as Crusher might have been. I didn't really get it.
Because Diana Muldaur didn't want to be listed in the main credits. It was negotiated into her contract, and probably was influenced by her pay. I won't pretend to understand the intricacies of Hollywood actor pay negotiations and billing, but that's how I understand the situation.
