Try use a third-party tool like WinRaR or 7-Zip. It might be because of the tool you use to extract them aren't well supported.
Also, make sure there isnt anyfiles being blocked by firewall.
Just want to confirm that i've tested in extracting the folder and it works fine.
It does show there is a Headers warning error in the file, but i used 7-zip's test function to see if it had any issues and showed no errors.
