I sent you a PM, but I see there is also a thread here so I will answer again.
My assumptionn is that intiially you probably asked for a build in St P and one of the others. Then you changed your mind and decided you wanted one in Warsaw and one in Moscow.
The reason it left you with St P is that the software has to guess what you mean. First build = Stp, easy. Second build = Mos (say) easy. Third click is Warsaw. What does the s/w do? It could either say the third click is a change of the second one or the first one. The same thing happens every time you click a different build. Our s/w decides that you want to change the last one you entered, and therefore it will always replace the second build slot not the first (St P).
What you have to do is to always clear your Build orders out by clicking the X in the orders list. Now the s/w knows what to do. Actually, you only neeed to clear the StP build then you are OK.
