Firstly ensure that the icon in the save isn’t the same as the one you are trying to replace by loading it in PS2 Save Builder.
Secondly you must remove the corresponding save from the memory card if it is on there already. For games such as FFX or Kingdom Hearts etc that use multiple saves only remove the save that you intend replacing. If you not do this the Xport/Sharkport software will only send across the game data and not the new icon data.
