Hello there, leonafortner.
Good job for checking the Recurring Transactions page to verify that automatically sent invoices are not due to invoice recurring templates. When creating invoices, let's ensure that you selected the Save and close option instead of Save and send. If you've correctly saved your invoices and the same thing happens, a browser-related issue might have caused this.
You can try logging in to your account using a private browser (incognito) and try creating a dummy invoice sent to yourself and then Save and close. Check the email used if you've received an email. If it wasn't automatically sent, you can go back to the main browser and clear the cache. You can also try recording an invoice through other supported browsers to get rid of these kinds of issues.
Feel free to check out these references for more information about invoices:
Keep me posted on how this works. I'd be glad to help you through it. Take care!
