Undefined Index: icon-handbag oceanwp-theme-icons.php on line 525

I see these errors on Android Chrome Browsers.

Notice: Undefined Index: icon-handbag in /home/customer/www/[website]/public_html/wp-content/themes/oceanwp/inc/oceanwp-theme-icons.php on line 525

Notice: Trying to access array offset on value of type null in /home/customer/www/[website]/public_html/wp-content/themes/oceanwp/inc/oceanwp-theme-icons.php on line 525

I have tried:
Appearance > Customize > General Options > Theme Icons > [Font Awesome], [Ocean] and [Simple]

And also:
Appearance > Customize > WooCommerce > Menu Cart > Visibility = “Disabled on all devices” & Changing the Menu Icons

On Google Chrome Desktop Browser, I was able to narrow it down to:

<a id="scroll-top" class="scroll-top-right" href="#"><br />
<b>Notice</b>:  Undefined index: fa fa-arrow-up in <b>/home/customer/www/[website].com/public_html/wp-content/themes/oceanwp/inc/oceanwp-theme-icons.php</b> on line <b>525</b><br />
<br />

<i class=" " aria-hidden="true" role="img"></i></a>

So I changed the arrow image in:
Customizing > General Options > Scroll To Top
I also disabled the “Scroll Up Button”

In Google Chrome, it still shows up as above, even after clearing the cache.

On Firefox Desktop Browser, it shows the changes and displays:
<a id="scroll-top" class="scroll-top-right" href="#"><i class=" fa fa-chevron-up" aria-hidden="true" role="img"></i></a>
