I was ripping a 3 cd set, and the first cd had a ccdb entry, the second and third did not. After ripping the first disk, and loading the second or third disk, the track titles shown were from the first disk. Puzzled, I closed k3b, and restarted k3b. Loading the second or third disk showed empty track titles. I presume this means there was no ccdb entry for these disks.
K3b 17.12 beta has the same bug on Arch Linux. Maybe K3b should always clear ccdb entries when the audio cd is ejected.
