Explanations for newly uploaded transactions in a VAT locked period

Hi,

I (stupidly) forgot to upload transactions for my business reserve account for a period that is now VAT locked (I'm on the flat rate scheme). I uploaded them today, and they appear as unexplained transactions. However, I can't actually select the correct explanation since the period is locked.

The amounts and transactions are just a few pennies of interest, but I don't have the option to treat them as such.

What's the best way of addressing this?

Thanks,
Dan
