RQMExcelImporter: where is the execution result description when specifying"executionresult.dc:description" in cfg?

RQMExcelImporter 5.x and 4.0.5 tried.
In Sample Execution Result.cfg, it is:
===
// this configuration file will create a static testcase linked to a static configured test case which links to
// several results
// static test case definition
testcase.XLSArtifactID=B2
testcase.dc:title=C2
testcase.dc:description=D2
// static configured testcase definition with link to testcase
executionworkitem.XLSLink=testcase
executionworkitem.dc:title=C2
executionworkitem.dc:description=D2
// result definition starting at line 5 in the spreadsheet
executionresult.XLSStartRow=5
executionresult.XLSDelimeter=\n
executionresult.dc:title=B
executionresult.dc:description=C
executionresult.jzalm:state=D
executionresult.er:starttime=E
executionresult.er:endtime=F
//links all results to all of the configured testcases in the worksheet.
executionresult.XLSLink=executionworkitem
===
executionworkitem.dc:description=D2 (D2 in xls file is: This is a placeholder testcase)
executionresult.dc:description=C (C in xls file has various description, such as: This test reported fail, This test reported false and so on)
After exporting to RQM, I can see test case, TCER and test result are generated. However, I can not find any place in which descriptions for TCER and execution result are exported to.

In other sample with execution results such as [Scripts that create testcases with TCER.cfg/Scripts that create testcases with TCER.xls] etc, it all has executionresult.dc:description=xx, but there is no place for the execution result description(NOT step descriptions which have no problem) in the exported execution result.

Does anyone know what the result of executionresult.dc:description=xx is supposed to be in using ExcelImporter? Thanks
