Thanks for discovering this issue. I believe this is because of the difference between Europe and UK/US/Australia in regards to the decimal point.
We will look into the issue and release a fix as soon as we can.
Apologies for the inconvenience in the mean time.
I'm happy to tell you that there is a fix available on the App Store now - version 1.3.2.
Please let me know if you experience and further issues, otherwise happy driving!
