Document AI don't recognize parent label area correctly, and does it only on per line basis

[Maksim]

Good Day, I have an issue with Document AI. When I try to create Parent label, with child labels in it, it does not recognize whole area of parent label correctly, and only recongizes it on per line basis, with separate label for each. Can it be done somehow that it recognize both lines in one parent label insteand of dividing it? 

Here is example how AI labeled it.

Below I have provided example on how I labeled the "Training/Testing" datasets
