I'm sure you've probably already tried this, but just in case.

In screen 14 if you click on the "Elect Out of All SDA (Bonus)" button (just above the "Description of property" field).  This toggles you to the Miscellaneous Overide box and you can un-check the box "Elect out of SDA(bonus) for all eligle asset classes and automatically generate the election statement"

At least this has worked for me on clients who proforma'd the election.
