A static query is like taking a snapshot of the database at the time the query is created. Only the records selected when the query is first created will be included when the query is used in the program. The same constituents are still in the static query so you can easily find them again if the need arises. Sometimes the static query does not hang onto those flags that are added to those specific records in the query.
We are currently evaluating this issue and will update this article when we have more information.
