When SS is set to Estimated in Today's Dollars, it uses the overall inflation that you set on the plan tab immediately. In this case it is 3%. Then the year after they draw SS income it drops down to 2% growth, because the growth on the plan tab is set to 2%, which also matches the annual increase on the Social Security income tab.
When SS is set to Estimated in Future Dollars, it uses the inflation that you set on the Social Security income tab starting the year after they draw income from it. Changing the annual increase on the Social Security income tab to 10% or the Social Security growth on the plan tab to 10% won’t change anything until the second year of taking income. Changing the overall inflation on the plan tab to 10% won't increase the Social Security income.
