We found a duplicate website, tier price, customer group and quantity magento 2   


Just edit the product -> Tier price -> remove the duplicate tier price option ( Customer group , Website and qty ) , 
Like   .
You set site1 -> QTY 10 -> Customer group retailer -> price $10  

Now next price :-> You set site1 -> QTY 10 -> Customer group general  -> price $10   

Problem : Genral and retailer group will work same so remove anyone , If you need wholesaler customer then you can add next option .
