Indeed. It only seems to be a problem if you've used the hotkey-based method first.

A quick fix in your case would be to make the following changes to scripts/startup/bl_ui/, in the GreasePencilDrawingToolsPanel -> draw() method. Replace the following lines:

row = col.row(align=True)
row.operator("gpencil.draw", icon='GREASEPENCIL', text="Draw").mode = 'DRAW'
row.operator("gpencil.draw", icon='FORCE_CURVE', text="Erase").mode = 'ERASER'  # XXX: Needs a dedicated icon

row = col.row(align=True)
row.operator("gpencil.draw", icon='LINE_DATA', text="Line").mode = 'DRAW_STRAIGHT'
row.operator("gpencil.draw", icon='MESH_DATA', text="Poly").mode = 'DRAW_POLY'


row = col.row(align=True)
op = row.operator("gpencil.draw", icon='GREASEPENCIL', text="Draw")
op.mode = 'DRAW'
op.wait_for_input = True
op = row.operator("gpencil.draw", icon='FORCE_CURVE', text="Erase")
op.mode = 'ERASER'  # XXX: Needs a dedicated icon
op.wait_for_input = True

row = col.row(align=True)
op = row.operator("gpencil.draw", icon='LINE_DATA', text="Line")
op.mode = 'DRAW_STRAIGHT'
op.wait_for_input = True
op = row.operator("gpencil.draw", icon='MESH_DATA', text="Poly")
op.mode = 'DRAW_POLY'
op.wait_for_input = True

Yes, that fixed it.
