incomplete extracted result

Hi All, we have a 7 pages pdf which is a delivery note and we would like to get the item information on it.
There are 13 items but unstract only extract 6 items.
I can use the prompt to get the total number of items, meaning all the pages are extracted.

But for the details, it cannot extract all the data.
Here is my prompt:

Extract the following details from the text and format them into JSON:

Part Number: The value that appears immediately before "UPC:". Ensure it is not the value after "CPU:". (e.g., 960-001312, PC-LABEL, UCSC-C220-M6S)
Ship Qty
Order Qty
SKU
Description
Serial Numbers
Return the result in JSON format as an array of objects, each containing:

"part_number"
"order_qty"
"ship_qty"
"sku"
"description"
"serial_numbers"

item after "007" cannot be extracted.
is there any limitation on the output size?

Here is the json output for the above prompt
result.json

Start with the attached result.json, screenshots, and extraction prompt; compare the six returned items with the 13 items described in the issue. Trace the extraction workflow to determine whether the missing items result from an output-size limitation or another extraction failure. Done means the cause is confirmed and the handling of all expected items is addressed.
