ABBYY Flexicapture Administrator "Link to existing field" not working properly

Hi,

I have created a ABBYY OCR template with the following document structure;

The “Article_FC” and “Number” of the TableProducts Table are fields which are linked to the text fields “Material” and “Quantity”.

If I run a test, the Material and Quantity are found, but not added in the TableProducts;

If I click on “Add “TableProducts” Item”, then the found values are added. So I guess the link is working fine. But why are does two values not added automatically?

When I run this template with the UiPath studio, then also no values are added in the extracted information file;

I hope someone knows how to fix this.

Many thanks,
