Can You Change Time of Day Template Back to Default?

Is this possible? My issue is while using a custom skybox I bought recently. I noticed it worked fine with a Default Level but not when using Time of Day. Is it possible to remove the Time of Day Template from my level and change it to default?

I made nearly a whole level before I bought the skybox so I can’t really just delete it and make a new level in Default, unless there is a way to transfer it to a default level…?
