AIO WP Builder Problem with Aweber Form Integration

The Form widget does not properly create a Form Button widget component. Instead, an additional Form Input widget component of type Text and ID af-submit-image-9299429 is created. A 404 error results on clicking the ‘submit’ image which should be redirected to a custom Thankyou page. Removing the erroneous Form Input component and replacing it explicitly with a Form Button widget still results in a 404 error when clicking on the button.
