I've running v2.5.0 as well - and I'm pretty sure this worked in v2.4.0. I've got exactly the same behaviour. Best thing to do - raise a ticket with SmartBear. Good thing is you can still use the ellipsis button to launch the Get Data form and populate the field accordingly despite the fact the Get Data context menu to launch the Get Data doesnt appear to work anymore.
if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta
