Antti Turunen Thanks for posting your question in Microsoft Q&A. I assume you use Analyze Invoice action in Form recognizer connector and comparing it with Document Intelligence UI and found some differences. Any specific info about additional fields would be helpful.
However, I suspect Document Intelligence UI uses prebuilt model with newer version v4.0 (preview) vs older version such as v3.1 (documentModels/prebuilt-invoice:analyze) or v2.1 (/prebuilt/invoice/analyze) used in the connector and suggest you review form recognizer endpoint and version in the logic app. If you are looking to use prebuilt invoice model, follow https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/tutorial-logic-apps?view=doc-intel-4.0.0&pivots=workflow-onedrive doc and configure in the logic app and validate the fields with Document Intelligence UI.
I hope this helps and let me know if any questions.
