Hi,
1. There is indeed a problem in the view file for the display of the order statuses.
In the cpanel_orders.php view file, it's the code:
<span class="order-label order-label-<?php echo $order->order_status; ?>"><?php echo $order->order_status; ?></span>
which should actually be:
<span class="order-label order-label-<?php echo $order->order_status; ?>"><?php echo hikashop_orderStatus($order->order_status); ?></span>
We've applied that change on our end, so you can also just download the install package on our website and install it on yours to get the patch.
However, the Actions text is properly handled. You can see an example on our demo website which doesn't have yet the patch above:
monosnap.com/file/F5a7V63CINOZkU4PvnBkRXQTXl6Ar3
The order status is not translated but the Actions text is.
So I believe that you might have a problem with your translation file.
Please turn on the debug mode and debug language settings of the Joomla configuration and look at the bottom of that page for the language debug data. It should tell you if you have an error in your language file which would explain why some translations might be missing.
2. I would recommend to check the same way as with the "actions" text.
Also, we didn't change that page with HikaShop 4, so I don't see why it would be a problem coming from the code. A bug in the translation file is much more likely.
