SUMMARY From bug 474548 comment 15: "You're right. I'm experiencing this too. But if I install a new theme now, it correctly shows as installed. IMHO this would be a different bug and I think it has more to do with the transition from plasma 5 to 6, and KNewStuff not recognizing the previously installed items as such. Then, the filter is "working", but it doesn't have the right information. Would you be so kind to create a new bug report with this information?" EXPECTED RESULT Widgets from KDE Store installed on Plasma 5 are recognized as installed after upgrade to Plasma 6 SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.1 Graphics Platform: Wayland
