I don't think you can go back versions with Combo only, you have to install 10.13.1 first, then run the combo to update to 10.13.3

I am not a pro but here is what I did:

1. I already had 10.12.6 (Sierra)
2. Downloaded 10.13.1 media (it's a .dmg) and double clicked it, which installed it for me (you already have 10.13.6, which means you might need to create bootable USB media for installation if the above will not work).
3. Once completed, I downloaded the combo and installed it in the same way as above.

Let us know how it'd go.
