How do I mirror my EX4 to a remote PR2100

My Cloud OS 3 Personal & Network Attached Storage My Cloud EX4
1

I have created backup jobs, but they are creating special directories at the remote PR2100. Here is an example.
The directory on my EX4 is /abcd/
The backup job is creating the following directory structure on the PR2100:
/abcd/WNAGxxxxxx_copyjobname/abcd/
I want the files in /abcd/ on the EX4 to be stored in the /abcd/ directory on the PR21.
What am I missing?
