For those interested, i’ve got a fix for this issue. You have to edit the main file of the plugin : gravityforms-multiple-form-instances.php and append to the $strings array this values :
"id='gform_preview_" . $form['id'] . '_' => "id='gform_preview_" . $random_id . '_',
'gformDeleteUploadedFile('. $form['id'] .'' => 'gformDeleteUploadedFile('. $random_id .'',
