Crop tool has only one Grid size

Hello. When I open a RAW file in Bridge (to Camera Raw) I can adjust the Grid size using the Grid overlay (attached Crop Tool 01). If I then click on the Crop Tool the grid is 9 sections and the Grid overlay icon is shaded (attached Crop Tool 02). How can I adjust the grid to be much smaller when the Crop Tool is active? This only started after the latest update. Thank you.
