BUG: fr245M reports wrong getHeight() for all fields in "3 Fields B" mode (on real device, not sim)

On the fr245M device, in real life, getHeight() for all three data fields in "3 Fields B" mode reports a wrong height. 

For top and bottom fields, getHeight() returns 81 - and not the 86 in sim and documentation.

For the center field getHeight() returns 74 - and not the 68 in sim and documentation.

I also see issues in field, so I assume it's the same for the none Music fr245.

Please fix!
