On Spanish regional settings, the decimal separator is comma and the thousand separator is "nothing" or dot. The same happens in a lot more countries.
On my computer working on Spanish (Traditional) (I'm based on Spain) if I enter a number with my regional settings format on the Biomarkers it's not accepted (a sound plays telling is incorrect to enter a comma, but I was trying to specify the decimal part of a number).
Also, if I enter a number, it's multiplied by 10. For example, entering 12 on Blood Glucose, pressing Save, scrolling to the next day and back to the current, and on Blood Pressure appears 120 instead of 12. The workaroud is entering 1.2, scrolling and it's transformed to 12.
My email is obou at qualitec dot es.
