Test Measures and Comparing Test Runs

I'm trying to capture ui-driven tests with dynaTrace and compare test runs.  I'm seeing a couple of things that don't make any sense to me and hope somebody can help point out what I'm doing wrong.

I'm making the rest calls to set up the test metadata and start recording.  I'm using user defined timers to have the tests tell dynaTrace which test is running.  And then at the end of the test run, I'm making the call to stop recording.

Over in dynaTrace under Test Automation I see the tests under ui-driven tests.  When I click on a test, I see the test measures at the bottom of the screen.  It looks like I'm seeing multiple rows for what appears to be the same test measure.  For example, I have 5 rows for measure 'Number of resources - JavaScript'.  When I click on some of the rows, the chart displays a single datapoint.  When I click on other rows, I get multiple data points.  When I highlight all of the rows of the same measure, I see all of the data points plotted.

Here's my question–is this normal to see these broken out into multiple rows?  How is dynaTrace separating them?  Is it one per test run?  Or is there some other criteria, such as the test measure value that's causing this?  I've attached a few screen shots to show what I'm talking about.

Thanks in advance for any help or suggestions you can provide.
