When trying to enter very big or small quantity values, one cannot use powers of ten to do so. I tried 5*10^-9, 5e-9 and finally 0.000000005. At the first one, I could not even click on save, for the second one I got the error "Unknown unit: e" and when I entered the number with a decimal point, it worked. However, when trying to enter -0.001004±0.000023, the last digits of both numbers are cut off.
