Eastwood Flaring Tool Issue with Cupro-Nickel

I'm having issues getting good double flares using the Eastwood turret flaring tool with 3/16 cupro-nickel brake line. It's a two stage process, first form a bubble flare and second op creates the double flange. I've done them with this tool in the past with steel line but I've having a hell of a time getting a round result now. After the first op forming the bubble flare, the result is eliptical/oval when you look at it head on and on the backside which should be 45 degrees has a goofy step in it. The second op seems to create the double flange but the backside the nut seats on has a goofy crease. I've tried everything and talked to their tech support and they've never heard of an issue. I'm suspecting the material, which came from Amazon but am looking for feedback if anyone else has run into this. I think they will seal, but the goofy shape on the backside gives me pause.
Some pics from a test part. First two show after OP1 and second two after Op2.
