Archna,
I'm also getting the same behavior on our QuickApps for SP 2013 v.6.2. I have both Title and URL columns in my SP list, and I want to convert the Title column to a Hyperlink based on <%URL%> value. So in the "Link to" property, I entered <%URL%>. However, the page url didn't render properly, b/c it seems to append an extra comma (,) at the end or url.
Quest: Has this bug been added to your to-do list? This is still a known bug in the lastest version.
Please advise.
Thanks,
