using 1.1

When I point mouse cursor to military production number I get nice explanation how is production calculated.
But when I do same with social production or research, nothing happens.
Bug or lack of feature?

*Btw, it would be handy if few other indicators gave explanation, like income, expenses and few others that don't do neither.*

Also, I noticed that if you don't produce any ships or have no starbase, military production is wasted.
In that case pointing with mouse to military production number shows emptry "mouseover tip".

*Needless to say, in that case most optimal thing to do is to prioritise either social production or research to minimize waste.*

But other way around, when having no social production, is does get transvered to military use.

So why it does not work both way.
Is it feature or bug?
