Inconsistent Apexcharts-card Popup Display

Hi All,
I have developed a couple of apexcharts-cards for a dashboard which are inconsistent when the mouse pointer is hovered over the details in the graph. I have an hourly and a daily chart. The hourly displays all four figures when you hover over an entry, the daily chart only shows one of the elements of the group. This is the inconsistent behaviour I have noticed. How can I fix it?
I have included the yaml definitions of the charts, plus the grid energy import daily and hourly utility meters, which both source the same grid energy import integral, from the same physical power meter (Shelly 3 phase EM.) I have also added a couple of images of the display as the mouse hovers over the chart.
