Need an English translation for 2 errors when doing an item import

Over the years I have learned what most of the errors mean but these 2 are foreign to me. What do they mean? (and while we're at it - why don't any item import error messages include the item? Would make it much easier to pin-point the problematic items being imported)

Thanks

Hal
