Duplicated Product shows wishlist counter although not on wishlists

Dear Team,

I’ve set up new products by duplicating an existing one with the Yoast Duplicate Post plugin.

Now the product of which I made those duplicates has been on one whishlist and the Yoast Duplicate Post plugin seems to have copied this metadata, so all new products show “Wishlist = 1” in the Woocommerce product backend, although they are not on a wishlist.

How can I delete/reset this wrong wishlist metadata?

Thx for your valued help.

Best wishes,
Johannes
