File location (in lower screen) does not update when in Options sub-menu

[cwacha]

In the main menu the file location in the lower screen gets updated when selecting an NDS file (e.g. fat:/boot.nds). The same behavior would be expected when trying to assign an app to a button inside the Options menu. But when I open the options menu, then chose "No Button" or any other option, the file picker is shown again in the top screen, but the lower screen does never update and specifically does not show the actual location of the file nor PUB or PRIV sizes.
