Description

I've noticed that when I split my PDF via Firefox to have a smaller PDF (e.g. first 10 pages), openparse wont extract any nodes. Original PDF gets extracted fine.

When I specify table_args, it will make parser return some nodes, but all are identified as a table.

I am attaching the PDF, perhaps someone could have a look what's wrong. concept-vp4360-cz.pdf
