Addition:
When viewing it in the grid layout, the price that you entered in the ‘price’ field shows up correctly. However once you click on the item in the grid to go to the single product page, the price in the ‘price’ field is then added to the ‘variation price’.
Eg: Price ‘$30’, Variation price: ‘$30’
Price in grid: ‘$30’ Price on product page: ‘$60’
So it’s either set the price to $0, and have it show up as $0 in the grid view and the correct price on the product page, or have it as the prie $30, have it show up on grid view as $30, and have it as $60 on the product page!!!
