Percent off in QUOTES does not adjust to total, no notifications sent

Client quote with “percent off” did not adjust when the client declined some of the items and the final total dropped. So the 7% off full quote, -$500.00, remained at that amount when the client chose fewer rooms and the total was 1/3 less than before. This gave the client and extra 500 off of a small total and we lost out big. We checked multiple times and it was a percent not $. We also did not receive any notification that client had completed the quote or we would have caught this sooner.
