[Python] Python autocomplete popup: double mouse selection

I am creating an autocomplete popup in Python using a Listbox which pops up. One can navigate by using arrows and using Enter to select or use the mouse to select an option. The arrow navigation is working perfectly; however, when I use the mouse to select an option and I want to use the arrows again, it automatically selects the second item on the list. Here is the code:

import tkinter as tk

masterlist = ["Daniel", "Ronel", "Dana", "Elani", "Isabel", "Hercules", "Karien", "Amor", "Piet", "Koos", "Jan", "Johan", "Denise", "Jean", "Petri"]
global listbox_wiggie_index

def new_list_for_listbox(*args):
# When text in entry.wiggie is changed,
# "search_var = tk.StringVar()" will change, which will activate this function.

global listbox_wiggie_index

listbox_wiggie_index = -1 # Reset index every time entry_wiggie changes so listbox is updated

# Clean listbox_wiggie
listbox_wiggie.delete(0, tk.END)

# Get value of changeable search_var.
t = search_var.get()

if t == "":
# Hide listbox_wiggie
# If "listbox_wiggie.destroy()" is used, the widget will have to be created again
listbox_wiggie.place_forget()
return

else:
# Populate listbox_wiggie
t = search_var.get()
for e in masterlist:
if t.lower() in e.lower():
listbox_wiggie.insert(tk.END, e)

place_listbox_wiggie()

print(f"|new_list_for_listbox|New list was generated and listbox_wiggie was placed. Index = {listbox_wiggie_index}")

def place_listbox_wiggie():
# The listbox_wiggie should be already populated. It will be placed at the bottom of entry_wiggie

# Get coordinates of bottom left of entry_wiggie.
x = entry_wiggie.winfo_rootx() - root.winfo_rootx()
y = entry_wiggie.winfo_rooty() - root.winfo_rooty() + entry_wiggie.winfo_height()

# Place listbox_wiggie at the bottom of entry_wiggie
listbox_wiggie.place(x=x, y=y)
entry_wiggie.focus_set()

def listbox_mouse_selection(event=None):
# From: "listbox_wiggie.bind("<<ListboxSelect>>", listbox_mouse_selection)"
i = listbox_wiggie.curselection()[0] # i = integer
t = listbox_wiggie.get(i) # text of selection
print("|listbox_mouse_selection| Selection was made using mouse")
write_value_to_label(t)


def write_value_to_label(teks):
# Write selection to label_wiggie
global listbox_wiggie_index

label_wiggie.config(text=teks)
# Hide listbox_wiggie
listbox_wiggie.place_forget()
entry_wiggie.focus_set()
entry_wiggie.delete(0, tk.END)
listbox_wiggie_index = -1
print(f"|write_value_to_label|{teks} was written to label_wiggie")

def change_listbox_selection_after_arrow_press():
# Focus on listbox_wiggie after arrows are pressed
global listbox_wiggie_index

# Remove the selection highlight from every item in the Listbox, starting from index 0 to the last item (tk.END)
listbox_wiggie.selection_clear(0, tk.END)
# Select the new item according to the index "listbox_wiggie_index":
listbox_wiggie.selection_set(listbox_wiggie_index)
# Highlight the item as the active item:
listbox_wiggie.activate(listbox_wiggie_index)
print(f'|change_listbox_selection_after_arrow_press|Selector of listbox_wiggie was changed to = {listbox_wiggie_index}')

def on_entry_wiggie_key_press(event):
