Bro still not clear, can you brief in a step by step fashion,what you have done from start and what/how Zerodha has underlined that the action came from your side. Also requesting you to upload images in photobucket as everyone including myself won't be able to access the image site you are in now. Please do brief as everyone herein Traderji can understand crystal clear.
Uploaded it all again here for you. http://s945.photobucket.com/user/ra...v-133_00_45PM_zpsaa6fb662.jpg.html?sort=2&o=0
Basically they clarified that in Nifty futures CO if you have one open position then you can take another position and the RMS will allow it (yes even if you have one lot worth of margin!) and the second position if happens to be an opposite position then it will square off the first.
