ive had it too, its a bugg from igntion and has something to do with your locale. this worked for me: > [@\[Bug-2323\] number conversion Gateway locale(?)](https://forum.inductiveautomation.com/t/bug-2323-number-conversion-gateway-locale/45750/7): > > So changing the locale (or the date formatting in the current locale) will only change the behavior of being able to make saving the simulator program work in a reliable manner.
