I'll ditto the above replies and say they'll be fine, the roots are alive and spreading
underground is what raspberries do.

Bottom line do bare root berries normally leaf out on stems or from the root
So it depends. Most brambles (raspberries, blackberries as examples) grow a primocane which is just growth, and that becomes a floricane the following year which blossoms and sets fruit, then dies. This is the two year cycle for most brambles, but there are some varieties that will have blossom and fruit set on first year growth. While floricanes are blossoming, new primocanes are emerging from the soil surface and growing for the next year. It doesn't really surprise me as you may have been shipped live roots with a floricane attached that is now dead, and all in good order. It helps brambles to remove the dead floricanes in autumn or winter by cutting them at the ground.
