CSS don't copy over with Cloner

I installed and tried cloner to replicate a site to a new one in a multisite. I include below the settings I used to make it happen and it seems the CSS styles haven't copied over. You can see in the two images included the original and the copied site...

Why is this and how can we make it work in future uses (I'm doing 3 multisites this week and will need cloner or a mean to clone one site a second time).
