I'm playing as blue (currently Huns) fighting green (currently Mycenaeans), and have reduced their war desire to zero. 

If I wish to force their surrender, the meaning of the presented surrender term is not clear at all (see screenshot). I don't know if it's relevant to the terms presented, but the war was declared as a "surprise war". 

The term "Give Mykene" (a city I've already captured) is repeated 5 times with various differences - the meaning of some of which I might guess:

* I think the bottom one (grey row with two flags icon, cost 10) is due to a demand predating the war

* The third row (greyed out, checkbox marked, cost 43) is probably because I've already captured it, and must include this term due to pre-existing demand on this city. But then I don't understand the meaning of "cost 10" for the demand below and additional "cost 43" for the term to give me the city?

* The second row (cost 80), fourth row (cost 42) and fifth row (cost 42, checkbox greyed out) I can make no sense of at all...

Also, the "Give Outpost" row has no indication of where the outpost is or how to locate it. If there are multiple such outpost with a row for each - I have no way to distinguish between them.
