Duplicate error messages

I have created a coupon to automatically apply a discount, depending on payment method. When toggling back and forth between Cash/Check and Stripe payment gateway duplicate error messages are displayed at the top of my checkout page. The message is: “Sorry, this coupon is not applicable to selected Payment method”.
Similar messages are displayed for a role based coupon.

Can these messages be hidden? Why are they duplicated and shown multiple times as a list at the top of the page?
Thank you
