What you're seeing is not unique to you and is working as expected. There are a number of automatic things related to styles that have a high probability of changing or being removed in OO4. I think you've figured out what's going on though.

The best thing to do in this case is make sure automatic level styles is off from the start and after you paste something and see that that style is carried on, is to right then use the clear format option on that row.

If there's something specific you'd like information on let me know.
