Add New Device Button Missing

[Reizake]

Hello,
According to Release 254 I should, have the "add host device" with host devices as so:

I am currently on 264-1~bpo21.10.1 but I do not have the add new device button. any reason this would be happening? I just upgraded from impish 252-1 and did a reboot.

Fixed it, Cockpit-Machines was not updated with the rest of the packages.

sudo apt-get install cockpit-machines/impish-backports

this fixed it fine
