No items shown for discounts or orders

-- HikaShop version -- : 3.2.1

I'm having a strange issue where orders that are created/processed are not appearing in the "Orders" section of the back-end, even though they appear in MySQL. Same with "Discounts", but I see other things just fine, like customers and products.
Orders:

I have set error reporting to "Development" and enabled debug mode for the site, cleared the cache for the site and in my browser, and still, nothing.
I don't know what you mean by "provide the MySQL queries at the bottom of the page". Are you asking for the query used to get the list in MySQL? Bottom of what page?
When I go into MySQL, I view the orders table by clicking on it, which nets me the query of "SELECT * FROM `tbhwww_hikashop_order`". I have processed a few sample orders successfully and see them in the table in MySQL, but not in HikaShop.
I've attached screenshots again so you can point out what queries you're looking for.
The only plugin that I have that appears to be related to HikaShop is "AcyMailing : HikaShop integration"

Additionally, this now explains my confusion as to where my zones are! This is a fresh installation of HikaShop, and I was confused as to why I would be forced to create all of my own country zones. I just checked, and they're ALL there if I look at it through PHP MyAdmin , including the one that I created because it was empty.

Below are the results for the Orders page, the queries for the hikashop_orders page, as well as screenshots of those from the Zones editor page for hikashop_zones.

Switching to a different browser or session works!
