I would not call this a bug. It is more related to Reckon assuming the type of account or product selected can not receive a cash distribution.
Before reading this thread, I was not aware that so many different types of investment products were provided in Reckon. After reading, I wonder how useful they are, as a more general investment account can probably support most securities. It is not unusual for providers of these specialist funds to change the rules !
I have an aversion to securities that provide unusual or capital or non-taxable returns, as when it is time to sell, it is a nightmare to resolve the capital base for capital gains calculations, assuming you did make a profit. The extra fees the tax accountant will charge probably erodes any capital gains that occurred !
