First, get Windows to stop lying to you about file extensions - it will make the following instructions far more comprehensible (In the explorer view you show as a screenshot, click "View" then "File name extensions").

Next, rename the "Ubuntu.vbox.vbox-prev" file to "Ubuntu.vbox". The existing 0 byte Ubuntu.vbox file should be deleted.
