Missing last row when package is run as a job from SQL 2008 R2

I have one package which reads a CSV and fills a table. This is a simple extraction. When i add the package to the server storage (SQL 2008), make a job en run it from that job, there is no problem.   

When I make the same job at our SQL 2008 R2 server and i run it, i'm missing the last row. It happens with all CSV's. When i run the package directly from the storage, there is no problem. So it only happens when its started as a job.

Is this a bug? Or am i missing something?

Thanks in advance!
