VAT accounted for in wrong period

Unfortunately an opened topic got closed when it wasn’t completed so I’ve started a new one.

I needed to change the invoice a bank transaction was attached to as I originally added it to the wrong one. When I did this, even though I told it to keep the same date for receiving payment it’s added it to the current VAT period rather than keeping it in the last period where it has already been accounted for and paid. It’s now showing up in this period’s VAT return when it shouldn’t be. How can this be resolved?
