Problem:
When trying to save form configuration in WPForms under settings -> notifications -> Advanced -> File Upload Fields, the selected files to upload disappear after saving.
Solution:
If you're experiencing this issue, we recommend you try the following steps:
1. Edit the

/wp-content/plugins/wpforms/src/Pro/Admin/Builder/Notifications/Advanced/Settings.php

file.
2. Look for line 205.
3. Comment out the following code:

// $output .= sprintf(<br />// '<input type="hidden" name="settings[notifications][%1$d][%2$s][hidden]" value="%3$s"/>',<br />// $notification_id,<br />// $field,<br />// esc_attr( wp_json_encode( $saved_value ) )<br />// );

After making these changes, please try to replicate the issue. This solution has been tested on a sandbox site and works as expected.
