Open the genealogical report you want. The left icon in the tool bar of the right pane says "Items to Include" Click on that icon. This opens another pane, on the left there is a list of items, in the middle there is a +, X and and up and down arrow. Click the +, This opens another pane with a list of fact. You can highlight (Include) as many facts as you like. I usually Click "Select All" at the bottom as why put facts in your database if you don't want them in the report. Click OK, click the items you want on the right of that pane and then click OK you are back to the report window.
One word of caution. I find it best not to save report settings. This sets up a series of setting that will be used for all reports. You will then spend an hour or so trying to figure out why you can not get your next report to look like you want it.
