Zone boundaries no longer accurate

Since the 2024.2 update my zone boundaries are no longer correct. I have a user that is well outside the zone boundary but is still showing as being inside the zone.

From testing I have to reduce the size of the zone dramatically before the user shows outside the zone.

Here is the zone, user is well outside the boundary but still showing inside the zone. Rolling back to the previous version of HA and the zones are accurate again.

To get the user to show as outside the zone I have to make the zone around half the size it used to be.

Is there some kind of padding added to the edge of the zone now?
