I have 2 stocks in my portfolio, Nvidia and TSMC, both of which show "NA" for Average Annual Return (%) YTD. I have seen this kind of thing before if any transactions occurred in the stock after the new year, but there has been no activity on either account. As you can see from the image here, ROI (%) YTD is calculating fine. Is there anything I can do to fix this, or is it a bug?
