QS7.5 Run Smaple job error: EXGROUP option error

[daxinz]

I used successfully QS7.01 for almost two years. We have just installed QualityStage 7.5.1. I copied the sample project QUALITY, and removed all the stages, but keep the DEM06. I modified it to a MATCH job.

renamed the INPUT to INPUTA, and copied it to INPUTB.
removed all the setting in Report
set the Extract: the Match to MATCH6, DUpA to DUP6, and ResA to RES6.
MATCH6 and DUP6 both have some key fileds from both INPUTA and INPUTB, plus @WET @PASS. RES6 has only a few fields from INPUTA.


I have two questions for
1) in the Extract setting, the MATOUT is always there, and no way to un-select it, because the <-GroupAll button is grey-out.
2) The project can not run, the log file DEMO6.Step001.log tells:
pid=2916
unrecognized option -EXGROUP
usage: see the user guide

Please teach me what is wrong.

Thanks
