This does look off. I think this is the block in question. The black numbers are the cut sizes you indicated, the red numbers are the finished dimensions, using a half inch seam.

Did I understand this correctly?? If so, no, they don't add up. Before suggesting a solution, what are the cut sizes of the plain framed blocks? since everything needs to fit together, need this dimension too. Have you cut everything?
