Could someone alter this script so that it uses the default KOs and WOs?

This script is from the Roblox Default Template 'FFA/Team Arena'. Could someone alter it so that it uses the default KOs and WOs instead of using a newly created model called KO - WO - A. This would be really appreciated! Also Configurations.GRANT_ASSISTS is false so don't worry about that. I have spent around 5 hours trying to find a way to make it run on KOs and WOs but was as you can see futile. Thanks for your time.
