Bootstrap kills form caption

I was going back and applying bootstrap to my project.

I have some child forms that I want the user to be able to move so that they can see what underneath it. That was working fine.

When I applied Bootstrap to it, the caption/title disappeared. I don't much care about the form caption itself. But I would like the cross (close) and the ability to move the form, back.

Is there a way I can do this?

How do I reproduce this?
I applied Bootstrap to our demo Demo\Basics\Multiform and can still see the child form caption when opening it with caption.

Sorry, its not reproducable. I have updated TMS stuff since then,
