MDG directed relationship when create the opposite way

[Guillaume]

Hello,

I defined an MDG with stereotyped ArchiMate elements and custom relations e.g. between 2 stereotyped ArchiMate_CommunicationNetwork (TypeA, TypeB) I can create a stereotyped Composition based on the Quicklinker and Metaconstraints.
When I use the quicklinker from TypeA to TypeB, I get the expected result having selected "composed of".
When I use the quicklinker the opposite way from B to A and select composes, I get a composition as expected but instead of having an unspecified direction, it is set to Source -> Destination. I can't find a way to prevent that.
With other MDGs I get the same issues with links like Serving, Association, etc.
Note: all stereotypes have the Class metaclass with the hideumlinks = true and a specialization link to the ArchiMate stereotype.
