The above suggestion will turn on Preferred Facts for ALL Facts.
If you want to leave the Global choice to be preferred facts, but only this particular one to list ALL instances of a fact:
1) Items to include
2) Select the Fact in the left panel
3) Click on the "options" box at bottom of panel
4) Uncheck "preferred fact" for that particular fact-type.
5) Click OK-Ok.
This is an override to the Global Preferred Facts switch, when the Global switch is turned ON. It has no effect if the Global switch is unchecked. (then all instances of all facts will show.)
