Start filters do not use them. when you update the PI it automaticly brings over the same information from the start filter. It was not bringing over ALL the information from the start filter some vendors uncheck themselves, so thoes vendors did not get updated.
Not using a start filter and updating the PI using a filter at the end works because it is using the choice you made at that point and not reading an INI file from the start.
in answer book under do not use start filters in V8 PI
