While looking at another person's question on the Lifetime Planner I ran into a strange behavior I can't explain, and wonder if anyone knows what is going on.
This is about the RMD amount. I have stripped down only one traditional IRA account and changed my wife's age so it will be far in the future to try to isolate the problem.
2028 is when I will be 70 1/2, so I will start there.
As I understand it the "Total Excess Min Distribution Investment" line is where this is reported (which lines up correct being zero in 2027).

2029

2030

2031

So why would it go to zero in 2030?
