Reset form doesn't work for me on the Multiple Files Upload tag

I have a form with many form fields, and there is a Multiple Files Upload field which is treated to look like a standard Bootstrap button. Everything works well, on Submit the data is uploaded to the database and the files are uploaded to a server folder, and the form is reset on Success, except for the displayed images which stay on the page, how can I clear or reset them? Am I doing something wrong?

Here are a couple of screenshots to show what I have done.
