If you have a field that you want to stretch with overflow text (so that now data is cutoff), first right click its field box and select Properties.
In the Properties window, navigate to the Text Field tab. Make sure the “Stretch with overflow” checkbox is checked.
When a field stretches with overflow, all the fields below it must be set to “float” down so that their data is not cutoff. To do this, select all field boxes below, and click properties. This will edit the properties for all of them.
In the Common tab, select “Float” for the Position Type.
