How do I edit or remove global discount pricing for all newer models?

Answer:

Once you open the Remora Administrative Portal and select Automatic Pricing under the Inventory Mods tab (glance at how to access automatic pricing), you can either change the percentage discount (pictured below) by inputting the new value or zero out the percentage field (previewed below) to remove the discount entirely.

After you are through with making the adjustments, be sure to click on the green SAVE CHANGES box (previewed below) that appears near the top of the page.
