Trouble in Iterating using Data Source Loop

Hello,

I am new to soap UI and I am having trouble regarding Data Source Loop.
My Project Structure is like this:-
1. Get Request
2. Data Source to Extract Information from Get Request Response.
3. Groovy Step to Modify the Data Source Step value.
4. JDBC Step
5. Data Source Loop(Data Source Step is Step no.2 and Target as JDBC Step)
I have created a X-path Assertion in JDBC Step. My Intention was to Iterate from Step 2 to Step 4 but it keeps on Iterating between Step 4 and Step 5.
I am doing something wrong here but not able to figure out.
please guide me how do I Iterate as desired.

Thanks,
Saurabh
