They haven’t vanished - they’re still there. QF0086, QF0089, QF0090 QF0099 for example are all there for 21/3 - 24/3, and marked as paid. If there’s a credit note against them, technically they cancel out (£10.00 and -£10.00 would obviously provide a result of £0.00, making them appear as if they’ve vanished). You can view all your invoices through Purchased > “Show All Purchases”, and then narrow down by supplier using the advanced search option.
Has the VAT return been submitted to HMRC? If not, you can roll it back and amend it. This would also unlock any transactions locked by it. I’d recommend taking a look at this guide in regards to this.
Deleting the credits (if possible) would obviously correct your P&L. Any VAT errors however can be adjusted in the next return, should you be unable to roll the return back.
