I have my home mortgage in the debt reduction plan, and am making extra mortgage payments, with the plan to have the mortgage paid off in another 30 months (end of 2028). I'm also working on the lifetime planner (I think the potential of the simulator graphs is great). Note: I do not include any credit card accounts in the debt reduction plan because I pay them off in full, every month, and have for years.
When I put the debt reduction plan into the lifetime planner, while removing the mortgage loan from the lifetime planner, it fails. When I look at the annual bar graphs, it takes 'this year's' "special payment" amount (the debt reduction payment) and extends it forever into the future, rather than have it vanish at the end of 2028.
The only way I can make the lifetime planner sort of work is to exclude the debt reduction plan, include the mortgage loan, and define a balloon payment in 12/28 to payoff.
