Okay, I spot checked the latest release and with https://github.com/ammaraskar/faa-instrument-approach-db/commit/2aef29b285955f4e43a2dabb3d36868a570487 this is mostly sorted.

Only three plates are broken, one of which is https://aeronav.faa.gov/d-tpp/2407/10311R2.PDF (RNAV (GPS) RWY 2 @ BYL) where they don't seem to have a - to separate the altitude from visibility.

https://aeronav.faa.gov/d-tpp/2407/00362R12.PDF (RNAV (GPS) RWY 12 @ SLN) and https://aeronav.faa.gov/d-tpp/2407/05799IL13.PDF (ILS or LOC RWY 13 @ STC) where the text seems to have been doubled up.
