Set Designer

Thanks so much for quick response. Tried everything you suggest: shifted the drawing label to no avail; went to Edit Crop, but it didn't help because when I'm in there, there's nothing to grab onto and drag. Attaching perhaps a more clear screenshot of the dilemma: this is what I see once I have clicked Create Viewport: my actual 2-D object intended as a viewport is that large thick circle. And then there is this giant odd orange area which I can in no way diminish, at the bottom of which, you are correct, is the drawing label.

Dear forum, For some reason, when I create a viewport, cropping no longer happens and I no longer get the alert which asks me whether I want to use the 2-D object as my crop. I must have hit something by accident to make that go away. As a result, my viewports are coming out on the sheet uncropped! and I don't know how to fix that. Would be so grateful for any advice! thank you! Attached is screenshot of my uncropped viewport as seen on the sheet layer
