You will have to dig out the bread to remove the blades. I had trouble like this with my breadmaker. I now wait until the final rise starts, (about 2 hours on my machine), tip the dough from the tin onto a floured board, remove the paddle and return the dough to the pan for the final rise and baking. The bread comes out easily and only has a small hole in the bottom of it. instead of a large one.
