At the top there's a black number for what we assume is the PV live outturn, and a yellow number for what we assume is Nowcasting outturn. However, the slash separating them makes it looks like it's the first number out of the second number (like how for regions it has the generation number out of what we assume is the installed capacity). You may want to instead separate the black number and the yellow number with a vertical bar | or something else to make it clear that it's a separator rather than division.
