The dropping of the first digit is happening in all three apps with macOS Monterey (not Ventura) and it only happens when I double click on a value to change it and start typing in the new value. If I use the tab key to navigate to the desired field and begin typing in the value, it doesn't happen. If I click before or after the value, which automatically selects the entire value including the measurement text, I can start typing in the new value and the first number is also not dropped. In the attached screen recording I am attempting to type in the value 456. On the first attempt, you will see the 4 is dropped as soon as the 5 is pressed.
