OCRspace web page - faq says no limit but 5mb. Error message says reached page limit

Hello I attempted to ocr test my Table of Contents (15 pages).

File size is 1.4mb. It said there is a page limit but the FAQ says no
restrictions as long as file less than 5mb. Is the FAQ out of date? or
am I doing something wrong?

OCR engine 5 was chosen

The free OCR API plan has a 1MB file size limit.

The online OCR demo page has a 5MB file size limit.

That is what the FAQ says, but I am receiving a message “page limit” and my file is less than the limited size (only 1.4Mb )
So why am I receiving the page limit error message?

I am using online OCR demo
