This happens during an initial setup of a new Investment within an existing portfolio. I am entering historical data as a "first-time" setup; entering data into FM from my Broker's records.
I chose to manually enter my (historical) Buys, then let FM retrieve and reinvest the Dividends [via right-click; Retrieve Selected Historical Prices].
FM is recording the Div Reinv as happening on the ex-date (and price). My broker records the reinvestment on the Payment date (and that corresponding price). I agree with my broker's method.
Feature or Bug?
