I don't use PNA in any form or fashion, and I would not expect Ancestry to "fix" it because in reality it can never be fixed, because it will always be wrong, since it can't support historical locations, border changes, place name spelling (or the actual name) differences based on religious and/or cultural differences among the current (or historic) population.
The FTM PNA is, as silverfox says, a "tool", it is however not a real "authority" in the sense that we use "name authority" in library science.
