SQL Server 2008 Fragmentation stats not updating after Reindex

SQL Server 2008 SP3

Thanks for reviewing my question.

I do periodic reindexing (not reorganizing)  and sometimes I will go in and review some tables and indexes for performance issues while doing some traces.

From the SSMC if I rebuild all indexes, on most tables I can immediately see the updates to the Fragmentation numbers. But for some reason a subset of tables and indexes will not show any updates to the Fragmentation number.

Interestingly enough, the Clustered index show zero and the non-clustered have heavy fragmentation.

Thoughts?
