Error when importing payments - Some of the invoices for which you've chosen to record payments do not exist. Please check and retry.

Hi,
New user here. Refugee from Wave's changes.

I'm now trying to import a subset of payments as I was receiving errors when trying to import a lot of payments.
The most common error by far is "Some of the invoices for which you've chosen to record payments do not exist. Please check and retry."
I have successfully imported my invoices and they appear to all be there and to be fine, so I can't understand why this error is being triggered.
