BOX File Automatic Generation using the word coordinates

I want to train tesseract 4 using images and ground truth text. I have generated the BOX file in for a page in the below format.

where i added the word coordinates for every letter as DATE  and Break the line using \t.

Here is an example of tif and box file. The problem that I have CTC compute failure and also when I try to generate BOX file from Tesseract i have the same issue.

How to make a valid BOX FILE for a Page.

Correct me if I am wrong, but shouldn't each character be bound by its own box? Try opening this in JTessBoxEditor ( http://vietocr.sourceforge.net/training.html ).
