If you have the first month of year set on Settings > Localization then it would start from that month.
I have that set to January.
The two unpaid invoices are from May and June.
So that’s not it, either.
Sorry, not sure. If you can provide steps to replicate I can try to debug.
I think I figured it out.
One of the invoices had been emailed prior to switching to Ninja, so Ninja doesn’t see it as having been sent, so it’s not including it in that total.
So, while it’s due, it’s not “sent”, and I’m 99% sure that’s the problem.
