Multiple discountValue Guid at order entry level issue

We have an issue In Production with few orders in which get 50% discount on Product if Price > 49.99 for qualifying Products . Order contains 7 items . Out of these 7 products , 2 items have multiple discountValue (means discount applied twice and thrice) . When we tried to search RuleBasedPromotionAction for these Action guid from flexi query , we didnt find any RuleBasedPromotionAction for extra discountValues. As a result of this issue , after discount few products are in negative Price .

We are not able to replciate this scenario in lower environment . Please help us on this . We are using hybris 6.6 .

Thanks, Nikhil.
