I've tried this in both the Online and Desktop programs and don't have the same experience. If I first select that I have an inventory and then go back and say I don't, The change to "No" sticks. If I say I have an inventory but don't enter any numbers, nothing happens. I have no issues or error messages. If you are getting error messages about this, I'd recommend deleting the Schedule C's completely and starting them over. If you aren't getting errors, I'd just continue filing my return.
