I too found almost all the data I'd input in Investments missing when I tried to edit it. Incredibly frustrating! Then I discovered the "step by step" feature in the "forms" view, and tried to change directly in the form. TT wouldn't allow it! But then I noticed on the left side of the screen a miniature view of what I was trying to fix. I made the changes there, and lo and behold, the main form changed too.
