I can't modify the zone

Hi, i can't costumize the zone stamp. why? I can see it in the preview but when i press ok it doesn't change.

Sometimes this Zone Stamps have separate settings for different scales (1:50, 1:100, etc.). I can't see much in your posted picture, but try to browse through the Zone Stamp settings UI and see if you can set the settings for used scale. You seem to have your floorplan at 1:50, so you would need to find the settings for 1:50 scale.

AC26, aren't Zone Labels used by default over Stamps?

Since v25 the default settings are set to a Zone Label, but through MVO settings you still have the option to Show Zone Stamps.
