Cant Delete a picture *Screenshots*!

[MinorInfluence]

Ran into one of the most confusing problems Ive had with a camera.
Been using my dads Nikon Coolpix L100 and i have 1 picture that wont let me delete it.
Doesn't have the option to delete it and i cant rename it or anything *see below*.
Any ideas on why this is.
Oh and i used Tracks Eraser Pro to try and shred the file (its a file shredding program) but that doesn't work either.

Thanks in Advance.

neverneverneverever delete pictures off the camera or card through the computer.

unplug it, turn the camera on, go the set up menu, format.

Out of curiosity, why is it a bad idea to delete pictures on the card through the computer?
