Bug in Quote - Discount value keeps changing

Bug in Quote - Discount value keeps changing

Problem providing an overall discount on a quote.

Steps to reproduce:
1. Create a quote with 2-3 product items.
2. Provide an overall discount (eg: $2,000), use the Direct Price Reduction.
3. Save
4. Click Edit again
5. The Direct Price Reduction has changed to Percentage reduction, which means if you happen to add or change any of the row items, the overall discount amount will change because the Quote is using % and no longer Direct Price.

Can Zoho fix this so that the Direct Price Reduction remains selected and the amount, and not change to the % change?
