Hi. I'm pretty sure the vid you followed was based off my guide. If it's this video (Look below) then I made that guide. Don't worry about saving. The cloud save is your save related to steam, aka the real game. Your local save will be the modded one since it's not connected to the cloud, but rather your computer. Do not worry about saving at all, and if you have anymore questions.
If this is the video you followed, I'm actually really happy to see my guide mentioned like this.
