2 line checking invoice: botom right is missing: Save & delete options (down bank invoices Save works good)
I assume you are talking about a 2-line-per-transaction checking account register. If the Action icons Save, More, Split are missing, add them to the register by clicking the Register columns icon, located at the upper right of the register, next to the Balance column title. In the popup click to put a checkmark at Action buttons. Click Done.
BTW, pressing Enter usually also works to save a transaction.
