I confirm this bug and it happens possibly with all copy cards,tested with Clone and Vesuvan Doppelganger.

The bug also happens with Sculpting Steel ...

A problem of all 3 cards that "choose a name" when entering the battlefield the other 2 are Saskia the Unyielding and Sewer Nemesis and have code for that.

I made a test and used etb_ability() and event == EVENT_ETB_ABILITY and this worked fine (which is wrong to use as this is an "as enters the battlefield" replacement effect) but I am mentioning this in case it will help to solve the bug.
