Answer

The default textract feature will detect attributes, entity from table, forms or your queries. In your case, it seems the invoice contexts was not properly extract from the default model. You could alternatively try to

1. Build a comprehend custom model to extract the context, e.g. https://aws.amazon.com/blogs/machine-learning/part-2-intelligent-document-processing-with-aws-ai-services/
2. 
2. If your invoice format/size are consistent, may be able to  extract the invoice information based on the bounding box position.
Code example: https://github.com/aws-samples/amazon-textract-code-samples/blob/master/python/09-forms-redaction.py

3. Last, but not the best suggestion - format the invoice in a table or form
