No....it'a definitely a defect....i've had a number of similar issues in versions 2.3 and 2.4 and 2.5.
Can you please raise a support ticket with Smartbear? They'll want to know about this...what version are you running?
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 title of the post to something more descriptive? This will help people when searching for problems.
