In SelluSeller, an order falls under Problem orders state either due to:-
Insufficient stock, i.e stock is 0.
SKU is not available in SelluSeller. This happens in case if the SKU/Product is directly created on Seller Center and you missed to sync that manually in SelluSeller. To sync manually in SelluSeller go to configuration>>Marketplace Management>>click on Sync Product (respective to Marketplace)
3. To resolve problem order, search respective order and click on Resolve.
If product is out of stock, update the stock under inventory the problem order will automatically get release from to New orders tab and you can process it regularly.
If SKU is not available in SelluSeller then to get that product go to configuration>>Marketplace Management>>click on Sync Product (respective to Marketplace). Once the product is synced in SelluSeller search that SKU and resolve problem order.
