This is very interesting (never seen it before). Can you please check what the decimal sign on your computer is? (Is it comma or dot, etc).
A very small possibility is Sensor Problem, but not likely since the number resembles 49.7 Degrees. Please let us know how it goes.

Not sure how to check that but it should be comma since it is a german system. But yea i also think it means 49.7 Degrees.
