Because you lowered the threshold score. This is a known issue
mentioned several times on this list

Are you sure you lowered the threshold a month ago? Has cron/disabled
not been running? The issue with cron/disabled disables that member
the first time cron/disabled runs after the threshold is lowered to <=
4.

They won't and you didn't have to raise the threshold. When you
reenabled delivery, any bounce info was removed.

If a fresh bounce had arrived, it would have reset the stale score, but
cron/disabled which primarily sends notices and unsubscribes disabled
members after their warnings are exhausted also checks to see if any
enabled members exceed the threshold (in case the threshold is
lowered).

The issue is cron/disabled doesn't check to see if the bounce info is
fresh.


>2. Is there a way I can force all the scores to be reset now?


You already did by reenabling the members.

Note: I'm going to fix cron/disabled for the 2.1.10 final release.
