The "WITH ghost" IPS doesn't appear to have ghost pieces.

[gc-octopis]

I downloaded the "tetris-hard-drop.ips" file and used lunar IPS to patch it to a Tetris.nes file, but when I load the game, there appear to be no ghost pieces (though the hard drap does works), I've tried 2-3 times of re-patching the IPS (and double checked that I didn't choose the wrong IPS), but nothing changed. Do I have to do some settings in order to let it show up? the above image is a screenshot of me playing the patched game on FCEUX.

Can anyone help me with my problem? thanks a lot:)
