Visual Designer bug

I love the designer. It’s a wonderful tool. However, I found a bug. Whenever I try to create a form using the Design view and add a fieldset, all the elements disappear from the page.

I found another bug.
I am trying to use the visual designer with fieldsets and templates. If I add a template inside a fieldset, it does not show up either in design view or the code view.

Thanks for the problem reports, we will update the online designer in the nearest time.

I still cannot use templates in desginer.
