Discover KNewStuff erroneous updates?

Plasma 6.3.6

I have installed a Plasma theme called ‘Sweet Mars KDE’ in November. Discover says there is an update for it as of Dec 7 2025. When I go to the kde store page (https://store.kde.org/p/1393498) it says no change since January 14 2025. Same for the addon’s github repo. Why is Discover telling me there is an update?

thanks
