Invoices entered twice – how do I delete them?

So they are already in Q3 and now entered again in Q4?

But Q4 has not been submitted yet? (if you are subject to VAT, I assume you are) So you can just delete those invoices in Q4, right? Via the expenses summary and then actions (on the far right of the screen)</

How strange that I didn't have that delete option (or any other options) all this time, but now I do. Now I can make everything okay and submit my Q4! Best regards!
