Tkinter Notebook tab header background ERROR

I'm trying to change the background colour of tab headers and it works perfectly when I run the app for the first time however when I click on other menu buttons and turn back to page where the tabs are it doesn't even show the tabs! I can only see an empty canvas! How can I fix the problem? Can anyone help me please? Thanks in advance for your help

def ch_fr():
    frame_ch = Frame(screen)
    frame_ch.place(relx=0, rely=0, relwidth=1, relheight=1)
    WIDTH, HEIGTH = 1540, 821
    canvas2 = Canvas(frame_ch, width=WIDTH, height=HEIGTH, bd=0, highlightthickness=0)
    canvas2.place(relx=0, rely=0, relwidth=1, relheight=1)


    firstcolor = "#f36958"
    secondcolor = "#132d7d"
    style = ttk.Style()
    style.theme_create("th_chp", parent="alt", settings={
                       "TNotebook": {"configure": {"tabmargins": [2, 5, 2, 0]}},
                       "TNotebook.Tab": {
                           "configure": {"padding": [5, 1], "background": firstcolor},
                           "map": {"background": [("selected", secondcolor)],
                                   "expand": [("selected", [1, 1, 1, 0])]}}})

    style.theme_use("th_chp")

    notebook = ttk.Notebook(canvas2)
    tab1 = Frame(notebook)
    IMAGE_PATH = 'empty2.png'
    WIDTH, HEIGTH = 1540, 821
    canvas3 = Canvas(tab1, width=WIDTH, height=HEIGTH, bd=0, highlightthickness=0)
    canvas3.place(relx=0, rely=0, relwidth=1, relheight=1)
    img2 = ImageTk.PhotoImage(Image.open(IMAGE_PATH).resize((WIDTH, HEIGTH), Image.ANTIALIAS))
    canvas3.background = img2
    canvas3.create_image(0, 0, anchor="nw", image=img2)

    tab2 = Frame(notebook, bg="blue")
    notebook.add(tab1, text="Chapter1")
    notebook.add(tab2, text="Chapter2")
    notebook.pack(expand=True, fill="both")



   Chapters = Menu(mainmenu, tearoff=0)
   mainmenu.add_cascade(label="Chapters", menu=Chapters)
   Chapters.add_command(label="Chapters", command=ch_fr) #this is the menu button that open the tab page

THE FIRST TIME I RUN THE APP

AND THIS IS AFTER I CLICK ON ANOTHER BUTTON AND RETURN TO THE PAGE
