Don't know. Backup the file, delete the placeholder, and see -- would be my suggestion. I assume that placeholder was for the 5th security in your list (which shows the asterisk also).
I can see that it might not make sense for the 5-year 'total' to be -79% while the listed securities are almost all positive, but it is not clear what you are showing? Grouped by Account? Multiple Accounts? Selected securities? Cash? Closed lots included? All that is where the Investment Performance report Jim referenced can provide more details. You've offered nothing about that as to why it didn't make sense.
