[Mailman-Users] check_arch script changing owner

Using Mailman version: 2.1.33 packaged for cPanel.

Running the script I obtained from https://www.msapiro.net/scripts/check_arch changes directory and file permissions and ownership. For example, in /archives/private/:

drwxr-x--- 5 mailman username listname_mydomain.org

becomes

drwxrwxr-x 5 root root listname_mydomain.org

And the list then stops archiving.

Is there a way to adjust the script? Or run some command afterwards to set things back to where they were?

Thanks for any help!
