I had this exact problem. The solution is to go into the section with the prepopulated data and edit the individual entry that is creating the error. Open up the section that was imported and if you look carefully you'll see that each entry is longer than shows on your screen. Find the slider bar at the bottom of the screen and slide it to the right to reveal the end of the line. At the end of each line you'll see a "pencil" icon that allows you to edit the line. Find the box with the amount that is less than a dollar that is causing the error and delete the amount (since TT rounds down to zero anyway) AND ALSO UNCHECK THE BOX that indicates that you need that data (can't remember how it's worded now). Save it and the error doesn't show up any more.
