Delete a flat pattern?

[Legrand]

I have a sheet metal part that I can not flatten back out. This "part contains features that cannot be unbent" error has shows up in the master assembly, and the related drawings now, and it's making me crazy. I only added the "Flat-Pattern" to make the drawings more clear, but now I can not remove that generated flat pattern, nor can I seem to fix it sufficently to remove the rebuild errors.
Is there any way for me to delete this?

Thanks.

Sorry, I didn't see the similar question below. I searched for flat pattern, not unfold. I will try some of those suggestions first.

It depends on what you did after the sheetmetal feature. Even though it shows up towards the end of the tree, it is still a chronological issue. Use right click to see what children it has before you try to delete it.
