If the "Delete file after upload" checkmark is set under settings, the pictures seems to be deleted from the camera, but not in an entire correct way. The camera still "believes" that the picture exists but instead of showing the picture it now shows the text "Not able to display content". The pictures seems to exist in the camera's internal index of pictures but since they are deleted they cannot be viewed.
