When more than to upload fields are defined in a Content app or in a dialog, when the dialog is saved just one of the uploaded files is saved. Upload fields save many properties, this properties are saved in JCR as separately properties instead as node with this properties. To do it the docu was follow: https://documentation.magnolia-cms.com/display/DOCS62/Upload+field
Steps to reproduce
1. Create a content app with two upload fields (see attached example).
2. Open the app and create a new item uploading two diferent files.
3. Save the new item.
4. Open the item to edit it. Both upload fields are displaying the same file.
Both uploaded files are stored separately and when opening the item to edit, both uploaded files are displayed.
Only one of the uploaded files are stored in JCR, the last one.
Not using two or more upload fields in the same dialog.
