Document AI does not import line_item child labels

[RasmusHartvig]

Hi,
After exporting a dataset from one processor, we're seeing labels under line_item parent group fail to be imported for another processor, even though both processors have child labels in common.
How can we avoid this problem?
Thanks in advance,
Rasmus

OK, I think I found the issue. I believe there's a bug in the Document AI dataset exporter. Steps to repro:

1. Create a new invoice processor
2. Label a document using a child label, ie create parent label "line_item" and a child label "unit"
3. Export document and inspect json. Notice unit type "line_item/unit" within the "line_item" section.
4. Create a new custom processor, setup parent label "line_item", child label "unit".
5. Import document. Notice unit fails to identify. 
6. Label unit again.
7. Export document and inspect json. Notice unit type "unit" within the "line_item" section. This is the reason import didn't work.

So in order to successfully import documents from dataset of one processor to another, drop the "line_item/" prefix for all "type" fields using a text editor.

Document AI team, any chance for a fix for this?
