There's Lois's trademark darf tree in Witness.
Re the door number. That one was also as 105 in Witness and at least the Pilot. But at the same (!) time, her apartment is clearly not on the first floor. After all, in the Pilot, Clark hovers in front of it and then rises only one floor before he reaches the roof. So either he hovered on the first floor, which sounds like a stupid thing to do even at night, *and* her building is only a two story building, or the entire apartment number has been a goof since day one.
(There's also the fire-escape-bonding scene in Battleground Earth) And the scene in S1 where Lois takes a dive out of her window to fall at least twenty stories, well, nobody can explain that. Except by applying the shrinking potion from Small World.
Michael, who's just realized fact-tracking gives worse headaches than figuring out time travel.
