Incomes that don't exist

Hello

I'm new both to accounting and akaunting. I'm a small business owner.
I just created my first invoice, marked it as paid (by mistake), then deleted the payment under my invoice (right column) to "unpay" it. So I have no income, no transaction, nothing nowhere other than an unpaid invoice. But my dashboard shows sales that are more than the invoice (roughly twice the invoice value -- I use multiple currencies).

How can I fix this sales/income/profit number showing while I don't actually have it. I just have an unpaid invoice of roughly half this amount.

Thanks!
