Copying a plan doesn't work as expected

If I have two almost identical plans, I use "save as copy" to create the second plan. Let's call them plan A and plan B.
However, when the user tries to sign up to plan B, they see the short description for Plan B but the long description and sign up button remain linked to plan A.
Is this how it's supposed to work? I would have though when Plan B was created, there would also be a payment link available for plan B - am I wrong?

Hi

I don't have any clue why it has that strange behavior. Could you please check and make sure the plan B has unique alias (different with alias of plan A) ?
