I find this sort of confusing as well.

When you know you are changing an existing file, use the swap file option (press three vertical dots at top right). You will still get prompted what to do ( I don't know why because you have already said you want to swap the file)

You might want to check that the Title field on the Import Settings  dialog is  set to "Use Filename As Title" rather than "Guess Title from FileName".
