When making an entry using the Track Progress feature, if a user makes an error and selects the wrong type of progress (percentage vs pages), the user must change the value in the Read Status Progress Number field before they can switch the Progress Type value. If the user switches the Progress Type value without changing the Read status Progress Number value, the Save button accepts the entry, but doesn't switch the Progress Type value.
