I paid off a loan but it's still on the snowball table

This is by design. The loan will show up on the snowball table for the remainder of the month. Once the next month comes around, the account will fall off of the list. This keeps the payoff plan accurate for the current month. Use the "next month" button on the snowball table to see what the plan looks like without the paid off debt.

paid off, payoff, debt still showing
