The rounds in football tournaments are called differently in different countries and cultures. "Round of 8" and "Quarterfinals" are the two most common nomenclatures.

I personally prefer for the Goals to be separated, because I can more easily relate them to other events in the match, such as a yellow card/free kick or a substitution. But I can see how this will make the match report tidier, especially if you scored a lot of goals. I have sent the suggestion to the appropriate teams.

There are some free kicks in the live match animations that are taken almost from the corner spot. You may be referring to them? There was a visual issue recently, which caused all corners to show a yellow card for the player who took the corner. However, this was fixed in a previous update, and should no longer occur.
