[BackWPUp Pro] wp-config.php appears twice if "Use one folder above as WordPress install folder" is chosen

[superpoincare]

Describe the bug

wp-config.php appears twice if you choose the options

• backup wp-config.php, robots.txt, nginx.conf, .htaccess, .htpasswd, favicon.ico, and Web.config from root if it is not included in backup. (default)
• Use one folder above as WordPress install folder!

To Reproduce

Steps to reproduce the behavior:

1. Go to "Files" in "Add a new job"
2. Click on '.Use one folder above as WordPress install folder!'
3. Open the zip file and check wp-config.php appears twice, once in the top folder and once in the public_html folder (or equivalent like htdocs)

Expected behavior

Since wp-config,php is already included, it shouldn't appear twice.

System

• Linux (server), Windows (personal computer)
• Version 4.19.150-76.ELK.el6.x86_64, Windows 10, respectively.
