# Remove checkbox from prop in pie menu

I am working on a pie menu for texture painting but i've encountered something I do not understand.

The code and image I have presented below shows a pie menu with a prop that enables mirror brush on X axis, what I do not understand is that the UI does not look the same as in the panel.

How can I remove the checkbox that is presented in the pie menu to the right

import bpy

default_keybind = 'W'

# spawn an edit mode selection pie (run while object is in edit mode to get a valid output)

# label is displayed at the center of the pie menu.
bl_label = "Texture paint"
bl_idname = "paint.image_paint"

def draw(self, context):
layout = self.layout

toolsettings = context.tool_settings
#settings = self.paint_settings(context)
brush = context.tool_settings.image_paint.brush
ipaint = toolsettings.image_paint

col = layout.column(align=True)
row = col.row(align=True)
row.prop(ipaint, "use_symmetry_x", text="X", toggle=True)

def register():
bpy.utils.register_class(VIEW3D_PIE_template)
wm = bpy.context.window_manager

kmi = km.keymap_items.new("wm.call_menu_pie", default_keybind, 'PRESS', ctrl=False, shift=False)
kmi.properties.name = "paint.image_paint"

def unregister():
bpy.utils.unregister_class(VIEW3D_PIE_template)

wm = bpy.context.window_manager
# clear the list

if __name__ == "__main__":
register()
