Q: eCom Syndicator is showing up again my deleted eBay/sku grid items, why?
A: Please go to Settings --> Add Ons --> eCom Syndicator and uncheck the 2nd option to auto-create items in Sku Grid that exist in eCom Syndicator but not Sku Grid. This will stop the importing process.
This option is really only for people who need to import existing items into Sku Grid or who are using other listing tools that do not import into sku grid. And ended items do not self delete from ecom syndicator for 8 days, with this option checked, they would continue to get added back into sku grid. You can uncheck this option and then delete the unnecessary entries from the grid and they should not come back anymore.
