Changing result loses the information.
If I change a result from say volume by length to length only as a check and covert back, cubit automatically converts the trench depth and width to default setting. This is very dangerous. I would also suggest that if you have referenced something and then deleted the referenced item it should leave the value. (I had the height and width referenced in the calc sheet but its now deleted as I deleted my General Measures before issuing the BoQ for tender).
