Prestashop cart rules/ voucher codes

Question: 

Prestashop have a major issue with cart rules and vouchers codes when multiple codes are available, to date there is no fix from prestashop regarding this problem so how would this impact LoyaltyLion?
Answer:
You can reduce the priority of the voucher, if you set "priority" to a bigger number on the LL voucher rule then it'll happen after the other voucher rather than before
