I am currently using the June wordpress theme with the premium version of YITH Wishlist Plugin. When a user chooses to add an item to their wishlist it automatically adds it to the default list instead of letting them choose a list.
This functionality is described here: https://docs.yithemes.com/yith-woocommerce-wishlist/premium-settings/wishlist-and-multiwishlist/
I have reached out to their support team and they said it is an issue with the theme since it works with default wordpress theme.
