The default layout is configured to change colors for every other round. That is, round 1 is blue, round 2 is green, round 3 is blue, round 4 is green. This originally was intended to indicate that a deck change should happen. If you've modified the layout to display the values in Portuguese, it sounds like you probably need to modify it just a little bit more.
Each cell has multiple "Property Sets", which are configured to display at different times during the tournament. You need to make sure you've translated every Property Set.
Edit one of the cells that isn't translated properly. In the "Property Sets" section, select each Property Set and look at the "Contents". Make sure you translate the text in "Contents" for each Property Set.
