Upload Document with default save button does't work

Hi,

We are working on Appian 16.3 (appian cloud) and we have the following form issue: we have created a form that has a fileUploadField() component, we upload the document and then press the save button and when reopening the form the document has been lost.

In order to fix this issue, we have created a custom save submit button that saves the documentId to a variable so when reopening the form, the document is shown uploaded.

So now the problem has been tranformed into how to remove the default save button?

Any advice is appreciated,
Thank you.
