page.GetTables() throws System.ArgumentException

[jrichview]

Hi,
I am writing a POC app parsing a number of PDFs, and I'm iterating through pages calling "GetTables()". I have an instance where it's throwing an exception saying:

System.ArgumentException: 'An item with the same key has already been added. Key: 454.95667'

It looks to me like the previous page begins a long table and it flows past that page. The second page's table must be detected but somehow added as the same table number?
