mutiple assertions not working from datasource step

Hi,

I have response coming from REST request. Using datasource(as xml) to get multiple values from response. I have assertion test step to check each of these response values. It has multiple assertions. When I run, it displays first assertion 9 times being validated instead of 9 assertions.
here is sequence
1. REST API call request
2. Datasouce as xml to get response values
3. Assertion test step with 9 assertions to get values from step 2.
4. loop from step 2. to 3. to get multiple values.

instead of checking 9 assertions in step 3, it displays first assertion 9 times?

I checked soapui bugs but couldn't see anything.

thanks for help!
