[Inkscape-user] Perspective/Envelope LPE is clone-like

Hi Friends, I'm usinig the Perspective/Envelope LPE (in 0.92pre2 for about screen contest). I duplicated an object which I applied it to, and set it aside, because I wanted to test a certain edit, but not lose the original. However, when I edit the duplicate, the original is edited too, as if it were a clone. Should that be happening? Or am I doing something wrong?

Thanks, brynn
