PayPal Check - No Thank you Message after payment complete/redirect

-- HikaShop version -- : 5.0.3
-- Joomla version -- : 4.4.2
-- PHP version -- : 8.1.27

Seeing this issue on two sites using PayPal Checkout on identical configurations (Same HikaShop version, PHP, Joomla, etc).

The orders and payment come through but neither display the thank you message/confirmation to the customer afterward.

Where the message should be I'm seeing just a comment:

<div class="col"><!-- HikaShop Component powered by www.hikashop.com -->
<!-- version Business : 5.0.3 [2401251118] --></div>

No errors, just empty where the THANK_YOU_FOR_PURCHASE text should be.

No customizations in the after_end or other overrides for checkout.

This happens too with the old PayPal payment plugin, but it wasn't a big deal because most people stopped at the PayPal confirmation side and never continued back to the site. But with the new one, it never displays a PayPal.com confirmation and just redirects.

The thank you text shows if you use the Accept.JS (authorize.net) payment method so this seems isolated to the new PayPal Checkout.

Interestingly enough, on the other site (not the URL used for reporting here) where we have Google Ad and Bing Ad code in the after_end, that information displays so it appears to be processing the after_end. It just doesn't do the thank you text ) which we do have a custom language overrides for but then I don't know why it would have an issue with just PayPal and not Authorize.Net.

OK, knowing that it moved to the system message is what I needed to know.

I set the template to display that and it appears.

Why is that different from say accept.js?
