A question about Constraint Manager

    Hello all,
    In the Constraint Manager connected to Allegro Expert 14.2, after I
    creating a match group in Net->Routing->Relative Propagation Delay
    wooksheet, adding some pin pairs to this new match group, and setting
    the scope, delta:tolerance and target, I close the Constraint Manager.
    I open the Constraint Manager again. I change the target to another pin
    pair in that match group, then I find the attribute "parentGroups" of
    the old target disappeared.
    What's wrong?

    Thanks.
    Tom
