cart total rule in discount portlet

Issue

While publishing the Discount it's not showing as the cart total minimum account is required to fill.
Steps to reproduce:
1. Start Liferay DXP 7.4.
2. Navigate to Discounts > Pricing > Commerce.
3. Click on the "+" blue icon and create the discount. (Apply to and Type could be anything)
4. Navigate to the rules section > Add discount rule (Rule Type is Cart Total)
5. Click on Submit.
6. Publish the discount.
Expected Result: The "Cart Total Minimum Amount" must be asked for the filling of the amount before discount publishing.
Actual Result: While only editing the rules, it's showing that the cart total minimum account is mandatory.

The observed behavior is a known Liferay DXP bug which has been addressed in Liferay DXP 7.4 Update 92.
