[Beta2][UI] City Improvement Mouse Over info

I wasnt sure where to post this, but this is sort of informational post for new people that arent as familiar with the game (such as myself) and a suggestion for something that could be a bug.

There are many improvements which you can build that arent clearly defined as to what they do, but I just discovered something I didn't know. Once you put a city improvement into the build queue, if you mouse over the build queue you get an info card on that improvement! My question is why doesnt this also pop up while you are selecting the actual buildings to put into the queue?

Example: The armory says it costs 20 turns 100 gildar 5 materials and 1 Slot

But the "Provides" space is Blank. So its kinda shady as to what it could do, but if you put it into the build queue and mouse over it there you can see it allows you to train troops 20% faster. I just started testing out the Beta yesterday so I'm not familiar with all the improvements and terms in the game, hope this helps newcomers.
