Draw - Delimiting Zones to extract PDF Data

Hi,
I have some readable PDFs and I am using Draw to define zones using coordinates to extract data in chunks.
I am using 2 different type of PDFs, both readable. For one type, I have no issue, for the second one I am not obtaining the expected result.
What I have is a table with 3 columns. I defined 3 zones, one per column. When I open the file, the zones come all merged into a single column.
The scenario is the same with the other type of PDF, and in the first one it works. Each PDF come from different source.

Appreciate your help.

Kind regards,

Caganer
