Variable products show price of “0” in all products page/shop page

I am building an online shop. I noticed after adding some products, that variable products show price of “0” in all products page/shop page and I thought that wasn’t a problem because I didn’t add any prices to them. After adding the prices, they still show a price of “0”.

Plugins:

Any help would be appreciated
