Document AI Invoice Parser - different results in Training tab vs Test&Analyze

[wissil]

Hi all,

We're testing Document AI Invoice Parser processor for parsing .pdf invoices, and one thing I find confusing is that sometimes the "Train" tab has way more parsed data elements than the "Evaluate & Test" tab, given the same exact invoice. 

For example, if I open the invoice in the "Train" tab, I can see the `vendor_name`, `line_item_description` etc, while in the "Evaluate & Test" tab I can't see those data points parsed.

We would integrate with Document AI via API, so I'm wondering what results we can expect - the richer ones from the Train tab, or the more rudimentary ones from the Evaluate & Test tab. Also would like to understand why there's a difference between the two.

Thank you!
