My two Cents (usual caveat)
Before deploying do you see the signon statements....
If So
These could be generated because the data/library that you have in your job is defined on one of the servers,
Check if you have selected a server to run for the nodes in your job, generally this is default, however you can force it to run on a particular ws, if this is different to you deployed batch location it will generate signons....
Check your default server when you generate the code,
so many different posibilities...
