I have inherited a package that looks like this:

when I execute this package the "Delete All Files" and the Interface steps work fine. However the next three steps seem like they are not being executed at all. In the Operator log they show as being executed with no error, green checks for all the steps, but the expected results are not seen.
If I manually right click each of these steps and execute them individually, they work fine and I see the expected results. I don't even know where to start looking for this. Can someone please give me some pointers about what might be happening?
