This has been addressed elsewhere by folks more knowledgeable than myself, but yes, there is a door missing on the map, and the compass roses (compasses rose?) all got turned 90 degrees in post production (just always use the page top as North, and you're fine, I believe).
As for 'first printing', 'second printing', etc. There was only one printing, I think. There may well have been expectations that there would be future printings, but there was this little thing that came along called 4th Edition D&D, and that has actually managed to have some impact on the FRP gaming world. Perhaps it maybe had some effect on plans for the DCC line? I can't say for certain, since I'm only an observer, but it may have done....
