Hi Shannon, are you still experiencing the issue?
You can try the following:
1. From withing the Configuration Console, open the Change business object.
2. Navigate to the Forms section and open the form being used for Change.
3. Find the field with the problem and select it on the form.
4. From the field options that appear on the left, there should be one showing the type or mask as Currency. You should be able to change it back to Number, then save the changes.
