When the light table is activated, it displays the number of its entries. This number is determined right at the beginning and is never changed. When the number of entries changes, because an entry is deleted, there is still written the same number.
5.9.0 is very old now. Can you reproduce this problem with 6.2.0 pre-release AppImage linux bundle available here : https://files.kde.org/digikam/ Gilles Caulier

I tried digikam-6.2.0-git-20190613T125237-qtwebkit-x86-64.appimage, and it still shows the same behavior, So, the bug was not fixed, unfortunately.
The bugfix will be included in next appimage bundle. It will build tomorrow morning. Please wait Gilles Caulier
