Once the Form is edited the Inventory widget Quantity resets

I created a form to sign up for after school classes using the inventory widget.  People signed up and then I needed to make a change to the description.  The problem now is that the qty available is not taking into account the number of people who signed up prior to the change.  For example, there are 7 spots available.  2 people signed up and it showed 5 available.  I made a change and now it shows 7 spots available when really only 5 are.  

Please help with this.

Let me check this further in my cloned Form. I'll get back to you.

Thanks.

I tested further my cloned Form and could not replicate any issues with it. The count of the Inventory widget's availability keeps decreasing.

You can test the edit link of the Form:

We are unable to test your Form as it uses a live credit card.

Here is my test form:

Let us know if you are still experiencing any issues with the Form.

Thanks.
