Yeah the deploy button does not appear, although I see other options such as "run plant growth study" for instance for the greenhouse. I'm running KSP 1.2.2 on OSX, with Planetary Base Inc v1.4.2. I've installed it with ckan, but I have actually never seen that option, even with earlier versions and when I had it manually installed.
One weird thing: in the VAB, when dragging an extendable part, its extendable features are visible in transparency, so it's not like they do not exist at all.
