When a new Beacon is added to an existing Beacon collection, the Beacon does not refresh automatically.
For example, if a new Beacon is added to an existing Beacon collection with an occurrence count set to 3, users who have already exhausted that Beacon count do not see the new Beacon.
Info:
To make the new Beacon appear to your end users, refresh the Beacon segment to reset the count to zero. For more information, see Refresh a Beacon Segment.
However, when you have multiple Beacons in one collection, refreshing one Beacon segment refreshes all the other Beacon segments.
If you want to refresh only one Beacon segment, it's recommended that you create a separate segment for that Beacon.
