Thank you for the help.  Actually your "images" and those from George4Tacs are the exactly right "answer" to this problem, i.e. "use the special allocation tab" to manually allocate" beginning capital between partners, even withdrawals and distributions that are not based on the percentage.  
Still I would think that this solution is only for the users, who should take time to do this in order to get the accurate amounts.  I still think that the program provides the right boxes in the Input Screen, not Special Allocation, and that the program should NOT calculate this way, beginning capital amount per partner based on the Ending Percentage of this year, which makes everything wrong and which does not make sense at all.  
Nonetheless, I thank you all for the helps.  Thank you very much.
