Sketch v39.1 - Layers with Round Corners - Issue when no round corners are used

Sketch v39.1 - I'm getting an error where the layer does not update due to "Layers with Round Corners", but No round corners are actually used on that layer

Would it be possible that your layer might contain more than 4 points or with curves, right now we only support straight points
