Payment gateways being attributed in referral traffic

Hi everyone,

I'm seeing traffic and sales being attributed to payment gateways such as the ones below:

• portal.clearpay.co.uk / referral
  
• hooks.stripe.com / referral
  
• pay.laybuy.com / referral

I've tried adding the payment gateways to the referral exclusions list within Google Analytics. But I'm still getting sales being attributed to the above payment gateways. I've added the referral exclusions list below. Could I be adding the exclusions in incorrectly? Is there...
