Link on back of card strips characters

On the back of the Emeritus Lawyer flip card on this page (https://www.clsmf.org/pro-bono-attorneys/), the link we have added to the Learn More button won’t save as pasted. It’s supposed to be this accordion section link:
https://www.clsmf.org/pro-bono-faqs/?item=How%20do%20I%20become%20an%20Emeritus%20lawyer?

But after I add and save it to the flipcard, it becomes:
https://www.clsmf.org/pro-bono-faqs/?item=HowdoIbecomeanEmerituslawyer?

Is there some html or code I can add to the link section on the card to prevent this behavior?

The page I need help with: [log in to see the link]
