If ALL of these conditions are TRUE :

Subtotal  equals or greater than  19.8  

Actions Apply : Fixed Amount Discount for Whole Cart Discount Amount : 20

When I add my Coupon code on my Order it showing

26.76 + 30 = 56.76 (subtotal+shipping) 56.76 - 20 = ? Expected Result = 36.76 Actual Result = 35.36

This problem can be caused by Magento cache, you can clear cache and re-run indexer, and don't forget to clear browser cache.
