No, not editing the pro dashboard product add/edit template.
I have a TEST USER for vendor accounts (Use it to make sure everything is good before making it public update). So I clicked “Add Product” button on the vendor pro dashboard, and as I went through it, it showed three drop downs “Colour”, “Brand”, and “Size”. And in those dropdowns are random selections I’ve never added (Nor do I even know where to add them haha)
