For some reason Elisa can not find some mp3 files on my system, so I tried "Force filesystem indexing" feature and noticed that it is uncheked again after I restart Elisa.
STEPS TO REPRODUCE
1. open Elisa
2. open Elisa settings and enable "Force filesystem indexing" option
3. restart Elisa and open its settings again
"Force filesystem indexing" feature is disabled
"Force filesystem indexing" feature should remain enabled after Elisa to be restarted
Operating System: Arch Linux
KDE Plasma Version: 5.19.4
KDE Frameworks Version: 5.72.0
Qt Version: 5.15.0
FWIW it seems that the setting is saved and loaded correctly, but the UI is not updating correctly.
A possibly relevant merge request was started @ https://invent.kde.org/multimedia/elisa/-/merge_requests/201
This is happening with me as well.
