thats because the game requires the tabs to be in there and when you delete them it crashes the game server , if you wish to delete them you need to delete them in all 4 spots that are required in the database concerning items , such as RefShopGoods , RefShopTabs, ScrapOfPackagedItems and PackagedItems
