Orders placed on BSE and share in holding is NSE

When I place an orders placed on BSE(Equity), why do I get some stocks from NSE in my holdings?

Where did you notice this? The order will go to the exchange that you have specified.

Suppose if i buy 5 shares of INFY on NSE and 5 shares on BSE.
what will it show in holdings?
does it display separately for NSE and BSE?
