Duplicate Data at Destination

Hello!

I cannot explain why I have duplicate data being inserted into a destination table even though data coming in from the source is actually less.

The data come in from a Lookup transform into a Conditional Split transform. Let say 100 rolls passed through the Conditional Split into an OleDB Destination transform you would expect to get 100 rolls inserted but in this case I am getting 120 rolls returned when the destination table is queried. How that happened I cannot tell. 

What is it that I did not do well? 

Thanks for  helping.
