Created attachment 194769 [details] A sample SMW with multiple fields displaying properly, & the OS Version field empty DESCRIPTION `System Monitor Sensor` widget field 'OS Version' is blank in 'kdelinux'. STEPS TO REPRODUCE 1. In `kdelinux`, install desktop widget `System Monitor Sensor` 2. Configure it for `Text Only` Display Style 3. In `Sensor Details` tab, add the Text-Only Sensor `Operating System Version`, & then Apply/OK OBSERVED RESULT The resultant active widget shows an empty field for `Operating System Version`, instead of the relevant value extracted from `VERSION_ID` set by `kdelinux` EXPECTED RESULT This field should display the current running `kdelinux` build version, read from the `VERSION_ID` variable, eg, `202607281716` SOFTWARE/OS VERSIONS Operating System (available in the Info Center app, or by running `kinfo` in a terminal window): KDE Linux KDE Plasma Version: 6.7.80 KDE Frameworks Version: 6.29.0 Qt Version: 6.11.1 ADDITIONAL INFORMATION References: https://discuss.kde.org/t/is-it-possible-for-the-kdelinux-build-to-appear-in-the-system-monitor-sensor-widget/49024 https://invent.kde.org/kde-linux/kde-linux/-/work_items/737
