macOS 26 Games app – Achievement description shows incorrect text before unlocking

Hello,

I found an issue with the Games app on macOS 26 (Tahoe) when viewing achievements:

In App Store Connect, each achievement has different values set for the pre-earned description and the post-earned description.

When testing with GameKit directly (GKAchievementDescription), both values are returned correctly.

However, in the macOS Games app, the post-earned description is shown even before the achievement is earned.

This seems to be a display issue specific to the Games app on macOS. Could you confirm if this is a known bug in the Games app, or if there is a reason why pre-earned descriptions are not being shown?

Thank you.
