Walgreens reward balance pop up on Apple Pay

i have not linked my Walgreens Balance Rewards card/account to my Apple Pay. And here it is, every I time I try to use Apple Pay, it appears on the screen below my default payment card. I have tried to remove it from my Apple Pay/Wallet by removing the existing and add a new one. Doesn’t work. I know how to delete cards from Apple Pay but not my attached balance rewards from Walgreens. Also a Southwest Boarding pass from a cancelled flight. What???Can anyone help me and teach me how to get it off my iphone?
