Renaming iPod Classic 30gb 5th Gen.

Hi, hoping for help.

I have installed iTunes version 12.10.9 from here (thank you very much) after accidentally updating to latest which did not recognize my iPod Classic 6th Gen 160gb. Testing this old version with my old iPod which has the same name as my newer one. I've tried clicking on the name in the left column but nothing happens so I can't rename it. I'm on Windows 10. Any other suggestions? Thank you.
