V4.2.x Usernotes not working in admin under "Order Details"

I have found in v4.2.4 and possibly a versions back, that the Usernotes are not working as should in the admin under "Order Details".

To reproduce:

1. Click on Manage Orders
2. Click the modify icon on any order

Under the Customer Information, you will notice that if the user has usernotes, it will display as "Array".

To fix, go to your administration templates folder and in the following file:

orders/customer_table.tpl

At approx line 116

Find:

Code:

{$usernotes|nl2br}

Replace with something like:

Code:

<ul>
{foreach from=$usernotes item=entry}
{if $entry<> '' && $entry.flagged!=1}
<li>{$entry.note}</li>
{/if}
{/foreach}
</ul>
