RQM Excel Utility, External ID and linking to an existing Test Plan from a Test Suite

I'm trying to assign an external id to a test suite where the cfg file has the statement "testsuite.XLSArtifactID=A", and the spreadsheet has one row for each test suite including title, description, owner, custom category values and attribute informaiton.   Col A has values like TSsuite0003 as the external id.    The upload runs without error create the test suites with the assigned values.   What's unusual is its creating a custom section called "XLSArtifactID", which does not seem right or is it?    

Additionally i'm trying to link each test suite to an existing test plan with "testsuite.testplan=BF" in the cfg file and a value like urn:com.ibm.rqm:testplan:988 in column BF, but no link gets generated from the test suite to identified test plan.    Appreciate any suggestions
