          Filters on most fields (i.e. database fields and simple calculations which are evaluated in the database) are applied before returning rows to Tableau. So when you filter on LogType your index value does change. But filters on table calculations are applied after all table calculations have been evaluated. If you think about it, it has to be that way - it's not possible to filter on the results of table calculations before they've been evaluated! So the index() is reporting the position of the row in the resultset before any table calculation filters have been applied.
