Tile Molester only edits Graphics. To minimise redundancy, NES games store their graphics as 8x8 tiles. You won't usaully find the same tile in the same graphics bank twice, because that would waste precious space.

The two tiles of the giant ?-block is on top of the cloud graphic, and the third missing piece is the aforementioned tile duplicated.
If you edit one of these repeated tiles, you will also see the changes in the other tile that's a part of the block in-game.

Think of the clouds/bushes in SMB1. If you edit the bush graphics, you also edit the cloud graphics.

You can bypass this by editing tilemaps with a tilemap editor or a hex editor. Djinn Tile Mapper is one of these, but I do it by hand with a hex editor.
