I've attached a copy of your form - save the file locally, right click and select design. Reviewing the logic, it looks like the Field values in the Batch node should be whatever is in the last list item, given the way the logic in the form works. I added a test button. Since the issue occurs in the browser, publish the form & add an item to the repeating table. Click the test button - are all the field values populated in the new section I added? Does the form submit to the list? I don't see any issues in your logic, and you already confirmed that executing your submit data connection doesn't cause an error, so I'm at a bit of a loss, but this is where I would start debugging if it were my form.
