Good old non-UK regional settings problem. You are in Denmark so using different settings for decimal? At least math channels that need comma don't still work correctly with Estonian settings because these are different than UK.
I remembered that this is not the first time I've had this problem, but in another software version. At this point, it was possible to solve this annoying problem with this comma by using another keyboard character, but now there no solution to this problem !!!.
Whats to say - maths is cool if its working correctly.
