Help w/error: "part contains features that cannot be unbent"

I hope someone can help with this. First let me say that I'm not a sheet metal person, so I'm not very familiar with that function in SolidWorks. However, I have this part (see attached) that is giving me an error that says "This part contains features that cannot be unbent" and flags the flat pattern in the tree with red. The odd thing is that everything was fine until I added the last feature, "Cut-Extrude3" which puts a notch on the inside corners of each "leg". As soon as I added the notch, I started getting the error. No doubt it is something in the way I've applied this feature but I have no idea what it is or how I can add the notch without corrupting the flat pattern.


Any help from you sheet metal experts will be much appreciated,
