Not split words in a line when using scan table image

Hello,
I am using free OCR API to scan table. The result returned lines but the words field in line object is not splitted in to words.

Here are my response response.json

Thanks

I tried again but with isOverlayRequired=true, the line is splitted in to words but it does not seem right
