I'm working on a small TF2 map, and I've set it up to be a cp map, named cp_close. It's mostly done and good so far, except the damn CPs themselves. I set it up so there are two neutral, equal CPs across from each other perpendicular to the team spawns, and whichever team can own both at once wins. Simple. However, the second point is displayed as locked ingame, and when the first point is captured the game is won. I have no idea how it was set to locked, or how to trigger it to unlock or make it open from the beginning.
I know maps CAN do that, stuff like cp_steel show that multiple points can be opened at once, but damn if I can't find a good tutorial explaining all the intricate features of it. What I've got so far is based 100% on what's written in the Source SDK wiki article on control points, and that information is woefully inadequate. Could someone please help?

If anyone's willing to look at it, here's the .vmf and compiled map:
