It’s important to have an exact radius of 0.0135 mm for the circle in the below vid. But every time I enter it the app shows 0.014 mm instead. Is it just rounding that or it’s a fault?!

Hi Hamed,
in the background your exact data is stored. We limit the numbers on these labels, but in the back its the original number.
It’s annoying, because when you edit you actually get to edit from the one you see, not the one in the back - I’ve raised this issue before to them team.
