This is a bug from the alpha you are running, I believe (it's been a while). Fixed for the latest alpha coming in the future.
As for the other stuff being "missing" and whatnot, they may be mockups. And if I remember correctly, Atlas has been re-programmed a couple times in its history. Similar to how the civs keep getting revamped or tweaked, so the civ profiles are now somewhat outdated.
Keep in mind, this is a huge project with only 10 people currently active, most of those being gameplay balancing people. 1 graphics programmer currently active. A couple of very very key personnel on hiatus/extended vacation. A few people submitting some good patches on Phab, but all part-timers/hobbyists. And while I enjoy writing, I'm assisting in committing gameplay patches, got my own huge mod (Delenda Est), my own non-0 A.D. related writing projects, a full-time job at a factory, fostering kittens/cats, girlfriend, my laptop recently took a shite and no money to replace it (I'm typing this on my GF's laptop, which is not ideal for development and gaming, but it'll work for now). Now, take my situation and apply it to everyone else too (with their own challenges).
You seem passionate. Maybe apply some of that passion to helping us!
