RQM Imported Scripts are Overwritten

Hello

I have tried importing test scripts to RQM using the RQMExcelWordImporter however if I upload a new set of scripts, it gets overwritten.

This is the content of my .cfg file:
// This configuration file creates a test case with each test script and links them.
// The linking is accomplished by self referential data
//The input data is temporarily placed in the comments

testscript.XLSStartRow=2
testscript.dc:title=D
testscript.dc:description=D
testscript.steps.type="execution"
testscript.steps.description=G
testscript.steps.title=F
testscript.steps.name=F
testscript.steps.expectedResult=I
testscript.steps.property name="comment"=H

// A new Test Script starts when an empty row is encountered (if needed)
testscript.XLSDelimeter=\n

testcase.dc:title=testscript.dc:title
testcase.dc:description=testcase.dc:title
testcase.Section("myns:com.ibm.rqm.planning.editor.section.testCaseDesign", "Test Case Design")=J
testcase.XLSLink=testscript

I'd appreciate anyone's help.
Thanks
