Importing bond holdings from Fidelity, there is no cost basis. I click the yellow "!" triangle to make the correction. I am presented with an "Edit holding" dialog. Evidently unlike the regular "Investments" window, this one does not understand that bonds are dealt with in hundreds and that the "10000" quantity shown in Simplifi is really 100, not 10,000. As such, it computes the total value of the bonds by multiplying 10,000 by the value. (Or to put it another way, this stuff should all be divided by 100). For example, for a bond value of 80 it shows $800,000 as the "Total value" when it should be showing $8,000.
After entering the cost in the box provided and clicking "Update", the system returns to the investment screen and the incorrect value (and computed profit) are shown there as well. Upon refresh the proper numbers are generated.
