Sheetmetal Hem in Round Part

Please take a look at my attached part made in Solidworks 2017 and suggest how to get this part to flatten correctly.

We made the part in real life with a sheer/brake/roller and pliers.  Then I made what looks like a realistic model in Solidworks (attached).  However, when I flatten the sheetmetal part, the piece after the hem is missing.

I need this to work so I can send the flattened drawing to our fab house.  What am I doing wrong?

Thanks,

Kyle
