Vexing Problem - Hidden Video File - I can play it - I can't delete it

I've got a strange problem. A video I made in September of 2016 and have since deleted (months ago) suddenly showed itself in the import window of FCPX.

The deleted video can be played and shows up under "Cameras" as "CANON". (see screen capture) If you ask me, that's just the SD card that I've inserted into the side of my MacBook Pro. The strange thing is that I've deleted everything on my SD card many times over since September of 2016.

What is more strange was that I just now deleted the other video shown in this import window. It plays.

So, obviously these videos were put somewhere. But where?

I want to delete them - but simply don't know where they are.

Is there any way you could, say, right-click on the file (in the import window) and select "get info" to show the current location?
