When navigating away from a page using IonTabs, I never really leave...how do I get out?

I’m trying to learn Ionic/React. I put Alan Montgomery’s (Does ionic/React content) Notes code into an app with IonTabs. In other words, you can click on Notes and it goes to his code. My problem is whenever I try and navigate away from the Notes tab, I never really leave. IonViewDidLeave never triggers! Yet somehow I see the code from the other tabs mounting. How do I make it so when I leave the Notes tab I really leave?

Here is Notes code (based on Alan’s):

import { IonButton, IonButtons, IonCard, IonCardContent, IonCardHeader, IonCardSubtitle, IonCheckbox, IonCol, IonContent, IonFab, IonFabButton, IonGrid, IonHeader, IonIcon, IonItem, IonPage, IonRow, IonSlide, IonSlides, IonToolbar, useIonViewDidEnter,useIonViewDidLeave, useIonViewWillEnter, useIonViewWillLeave } from '@ionic/react';
import styles from './Notes.module.scss';
import React, { useEffect } from 'react';
import { addOutline, menuOutline, notificationsOutline, searchOutline } from "ionicons/icons";
import { getCategories, getNotes } from '../store/Selectors';
import { CategoryStore, NoteStore } from '../store';
import { markNote } from "../store/NoteStore";

const Notes = () => {
  
	useEffect(() => {
	  console.log('Notes mounted');
	  return () => {
	    console.log('Notes unmounted');
	  }
	  },[]);

	useIonViewDidEnter(() => {
	  console.log('ionViewDidEnter event fired');
	});
	
	useIonViewDidLeave(() => {
	  console.log('ionViewDidLeave event fired');
	});

	useIonViewWillEnter(() => {
	  console.log('ionViewWillEnter event fired');
	});

	useIonViewWillLeave(() => {
	  console.log('ionViewWillLeave event fired');
	});

	const categories = CategoryStore.useState(getCategories);
	const notes = NoteStore.useState(getNotes);

	const getNoteStyle = (categoryID, isComplete = false) => {

		const categoryColor = categories.filter(category => category.id === categoryID)[0].color;

		return {

			"--background": categoryColor,
			"--background-checked": categoryColor,
			"--border-style": "none",
			"opacity": isComplete ? "0.6" : "1"
		}
	}

	return (

figured it out!!! whew One of the tabs wasn’t using any ionic tags in it so it screwed everything up. It was just using a React mapbox component.
