Problem with Total Return Amount

Hello,

There is a very large discrepancy between the total return amount shown by default above the performance chart in the top left, and the return amount that pops up when I hover over the chart for today’s date. Why would there be such a huge discrepancy? The amount that pops up when I hover over the chart is much larger. Shouldn’t it be the same as the total return in the top left, if I hover over the current date?
