The pictures of the alien terraform machine says "Distribution of this item will result in court marshal". This should read "court martial". While "marshal" is a term used by the military, it is not used in this way.
On the computer screen that displays the schematics of the alien terraforming spaceship, some of the specs have the word "unknown" misspelled and they read "DEPOSIT UNKOWN" and "AGENT UNKOWN".
When SG-1 meets Lotan on the ship, Lotan seems to be aware that the beings on the planet are called Enkarans, but this name is not mentioned by SG-1 after being transported to the ship.
