Alexa, does not recognize Open / Close commands

Hi I have an Alexa issue remaining:

I want to give the command “Alexa Rolladen schließen” (Alexa, close Rolladen )
Issue: I get The message: “Rolladen unterstützt das nicht” (Rolladen does not support this)
The Lower and Raise commands work (Alexa Rolladen tiefer) but it seems it does not care about my mappings daying lower=-30 (see log, it lowers always 1%)
I saw several posts on this issue, but never a clear statement what the problem is and how I can solve it:

here my .Items

Rollershutter   EG_WO_Rollladen_Links_Proxy         "Rollladen Wohnzimmer links [%d %%]" { alexa="RangeController.rangeValue", category="EXTERIOR_BLIND", friendlyNames="@Setting.Opening", supportedRange="0:100:10", unitOfMeasure="Percent", actionMappings="Close=0,Open=100,Lower=(-30),Raise=(+30)", stateMappings="Closed=0,Open=1:100" }

.Log
