PR application National Health Insurance receipts

I just submitted my PR application and immigration gave me a list of documents I still need to submit. They ask for health insurance payment proof and it’s written a proof would be the receipts.
Unfortunately one of the receipts is missing….
I understand that I can proof pension payments with a document from the pension office but how can I proof my health insurance payments if I don’t have all the receipts anymore? I understand that they want to see the exact day I paid each month but if I don’t have the receipt anymore is there any other document (that I can get from the city office?) that shows the dates I paid?

Anyone applied without all the receipts (and just a statement why you can’t submit them) and still got permanent residency? I
