Sounds strange to me.
What you can do, when you start a table manually (select the "New Table" tab, then press the "Create Table" button), is to directly select if you want Conlony/Platinum. To do that, press the "Select Kingdom cards" button and in the lower left area are two buttons, one for using Colony/Platinum, the other for using Shelters. They are normally at "Random", but you can press them and change them to "No" or "Yes". If you change the button for Colonies to "Yes", your table will always use Colonies/Platinum.
