The following message is displayed in the Processing Notes:
"The Field "Field Name" from Flexilayout is missing in the Document Definition"
This warning indicates that there are still some documents in the project that are recognized by the old version of the document definition, which contains the "Field Name" field.
Most commonly, such documents are in training batches, recognized by an old template containing the "Field Name" field.
Please check your training batches and find the document recognized by the old template of document definition. Update those documents and the warning will disappear.
