NX12 lines and arcs associative icon grayed out.

Hello,

NX12.0.0 MP1

Anybody knows why the associative icon in the Insert -> Curve -> Lines and Arcs -> Associative icon is grayed out?

When I try to create a new line point-point with the above command the associative icon is grayed out and the line is always associative. If I need to remove the associativity I need to go to edit -> feature -> remove parameters. Very anoying.

Regards

Frank.
