I had no problems training with the ocr-d boxes. Looking at the tiffs the first thing I'd try to do is adding some white border on left and right.
For my training I used no-binarized (grayscale) data and I think it could be better (more information is available). Are you training from scratch of fine tuning a model? How many epochs did you do? How long did it run? Maybe you just need to wait more.
