Invalid fonts checksums and kern.Format0.rangeShift

I use fonts from this repository to validate my sfnt parser. I also use https://github.com/HinTak/Font-Validator/ to be sure that errors are in fonts, not in my parser (and sometimes I recheck by hand).
I have found that following fonts have invalid fonts (not tables) checksums:

- AbrilFatface-Regular.ttf
- CarterOne.ttf
- ContrailOne-Regular.ttf
- CreteRound-Italic.ttf
- DawningofaNewDay.ttf
- DeliusSwashCaps-Regular.ttf
- DeliusUnicase-Bold.ttf
- DeliusUnicase-Regular.ttf
- Gruppo-Regular.ttf
- Iceland-Regular.ttf
- JockeyOne-Regular.ttf
- JustMeAgainDownHere.ttf
- KaushanScript-Regular.ttf
- LaoMuangKhong-Regular.ttf
- LaoSansPro-Regular.ttf
- LobsterTwo-Bold.ttf

- RuslanDisplay.ttf
- SquadaOne-Regular.ttf
- TerminalDosis-Light.ttf
- Thabit-Bold.ttf
