Thanks for raising this again Sorry we didn’t get to it sooner.
I’ve just deployed a fix to sort this out, but it’ll only affect future transactions.
When we were working out that number we’d check how many scheduled payments you’d made. But we wouldn’t include payments where you’d paid your monthly amount early in the count!
Including them was a bit tricky. We couldn’t immediately tell whether a manual payment was reducing all your future payments (in which case we didn’t want to count it), or paying off your whole next schedule payment (in which case we did want to count it).
Instead, we’ve tweaked it to take the total length of your loan, minus the number of payments you have left.
So if you have a 24 month loan and you have 4 payments left, we can confidently say that your most recent payment was number 20, regardless of whether you’d paid some of those 20 early
Sadly it’s prohibitively difficult to go back and fix this for old transactions, but let us know if everything looks good on your next one!
