Permalink count's up

Hello,

I used the plugins wpallimport and woocommerce store toolkit. Last days I do some trail and error with importing products to woocommerce and deleting because of wrong import.

Now the import works fine, but I recognized mysteious permalinks. The links count up to “-6” for some Products. It seems to be 5 other versions but the trash im empty and there are also no similar products displayed on the products site. But mysterious – on this site under “All” there are 210 products counted but only 43 under published.

So I try to look at the database table wp_pmxi_posts but here also only exists the publishes products.

Has anyone an idea how to get rid of these numbers?
