From watching the Mill Creek set....I've seen at least three different show logos used, but only two were used in syndicated reruns. I did see one episode in syndication (but only one time) that used "The Adventures of the Nelson Family" as the title.

Just watched two episodes on the Mill Creek set that actually uses "The Adventures of The Nelson Family" as the title! one of them is "David, The Law Clerk". I wonder why they had decided after all that time to change the name of the show and then after a brief use, go back?
