We just upgraded our SQLBridge system from 7.7.8 to 7.9.4 last week. i noticed this week a few of our transaction groups that were set to retain data for 30 days had the data in there respective tables deleted at about the time the upgrade occurred.

I have the Store timestamp to: t\_stamp and the delete records older than: 10 day(s) setup.

I do have another datetime column being stored, but the name of that column in the database is EventStart and is just an expression SQLTag bound to the expression now().

any ideas what is happening?
