Delete Designer or Vendor from Each Individual Product

[ShopEvelynRhea]

Hi! I'm almost done completing my website for my boutique but cannot for the life of me figure out how to delete the vendor/designer from every single product without going through manually and editing each and every one which I don't want to do. I've pictured below what I'm talking about and appreciate any help!

Website: https://shopevelynrhea.com/

click on an item and it'll show you the designer or vendor. I want that gone!

I finally solved it!

How did you solve this?  I have a problem, I have created duplicated vendors and now I don't know how to delete the duplicated ones.
