Deck editor columns (and other woes)

Ok, stupid question time. I found no topic where this belonged so I started a new one, sorry.
Simple question: without source-stabbing, how the bloody heck do you make the "AI" column visible in the deck editor now?
It is set show="true" in my editor preferences file. It just fails to show up in the editor, and there is no in-game choice to display/hide columns.
I'm currently working on a potential new world and trying to optimize the decks for the AI...without this column, you can forget it. Not going to happen.
Also, the deck import dialog no longer seems to recognize specific set codes - previously you could specifically ask for, e.g., 5th Edition Ironclaw Orcs, by typing "Ironclaw Orcs|5ED" into the import dialog. In the current version of the import dialog, this simply causes the entire line to be unrecognized. This too makes world development quite a bit harder.
While I applaud the new functionality in the editor, I'm sorry to see that features that were extremely helpful when designing new worlds, were lost in the process.
