Webforms node fields not available in data select

Hi there.
I´m using rules 8.x-3.x-dev and Rules Webform 3.0.1 and trying to set the fields of the node which the webform is on by webform fields and fill these with webform data. But I can`t get this working because the data selector in the rules Event Webform submit does not show the fields of @node.node_route_context:node. And it is also not possible to do a direct input there which might look like this {{ @node.node_route_context:node.field_my_field }}. Is there any way to access the field data of the webform node and fill it with webform submission fields?

Thanks alot!
