Right now if I have a number entered like 4,000,000 and i delete the 4 to change it to a 3 the number collapses to 0 before i can enter the 3, making me have to enter 000,000 manually again each time.

This is really annoying. I want to be able to modify leading digits of a number without changing the rest of it because usually im only modifying the first 1 or 2 digits in large numbers
