Problems with Text.update()

[draxx0405]

I have this code but I don't know why this happens

The container where it has the text disappears, but the container where it has the iconbutton is visible when the mouse is hover onthe primary container.

import flet as ft

class PanelTextWithTime(ft.UserControl):
def init(self,BarColor:ft.colors,BackColor:ft.colors,TextColor:ft.colors,Time:str,IconColor:ft.colors,Text:str,on_Click):
super().init()
self.BarColor=BarColor
self.BackColor=BackColor
self.TextColor=TextColor
self.Time=Time
self.IconColor=IconColor
self.Text=Text
self.on_click=on_Click

def build(self):
    
    self.txt_Time=ft.Container(
        content=ft.Row(
            [
                ft.Text(
                self.Time,
                color=self.BarColor,
                size=15
                )
            ]
        ),
        visible=True
    )
    
    self.IconButton=ft.Container(
        content=ft.Row(
            [
                ft.IconButton(
                    icon=ft.icons.MENU,
                    icon_color=self.IconColor,
                    style=ft.ButtonStyle(
                    overlay_color=self.BackColor
                    ),
                    on_click=self.on_click
                )
            ]
        ),
        visible=False
    )
    
    def Content_hover(e):
        self.txt_Time.visible=not e.data
        self.IconButton.visible=e.data
        
        self.update()
        print("MouseHover: "+str(e.data))
        print("IconButton: "+str(self.IconButton.visible))
        print("txt_Time: "+str(self.txt_Time.visible))
        
    self.Time_content=ft.Container(
                    content=ft.Row(
                        [
                            self.txt_Time,
                            self.IconButton
                        ],
                        alignment=ft.MainAxisAlignment.END,
