I already had all coins in my wallet in one address but got them with several smaller transactions from the pool. I now made one new address and sent all coins to that address. Is a transaction within my wallet always shown instantly? It does not show an output and an input. It only displays the fees for that transaction on the right. Is that correct what I did?
You need to check your inputs using coin control, activate it from settings, then open it from send tab.
You should have one big input.
