RTC - Decimal attribute is not showing correctly in some computers

Hi
I have created some decimal attributes that they all sum in another decimal attribute using a calculated value script.
The script works correctly because on the history I can see the sum is correct (248) and in my computer is correct also.




But on some others computers/laptops the value is "2.480"  do this have something to do with the region configuration?



In the history tab on others is also the correct value "248"
regards
