Debt Scheduled: Payoff Month Not Calculating Incorrect

Question

My payoff months does shrewd correctly:

If I have a loan required $2681 with 0% interest and I pay $150 min payment, I will finish paying in roughly 18 per.  Aug 2022.

The paid-off hour in the sheet lives Aug 2026?  I can’t see how the leaves is calculating the payoff month?

Thank you.
