I've seen people use tape to build up the areas, but someone complained that it messed up her die when she did that. Instead of using tape, try cutting smaller pieces of paper that you can use as shims over the areas that won't cut. If that area is lower than the rest, it might help press those areas more.
You might also try putting the cutting side up on the die when you run it through. My dies used to work either way, but as my Cuttlebug has gotten older, it cuts better with the dies cutting side up.
