Hi Tim,
I am doing good.
I would suggest you to check listing source field in WLK1 table which will tell you the source of this record creation. So depending on the listing source value, you can take action to stop through assortments or layouts.
Also in WLK1, check the validity of listing records whether they are active or not. It is possible, the listing records which are not valid today are still there in the table.
I hope this will help.
Regards,
Amit
