My group and I are having a problem with Pathfinder 1e's character sheets. When trying to change a value in an attribute or skill, we'll type in the new value, but the sheet won't register it and apply it to the automatic calculations. A Strength score of 20 should give a modifier of 5, but if we change the value to 22, the sheet still says the modifier is 5. We'll have to change it 3 or 4 times in order to get it to work properly. This happens every time and applies to all numerical values entered into the sheet.
