Hello,
you did nothing wrong!

The breadcrumbs is a module which can be disabeld.

And this one is the page title and not breadcrumbs

Thank you, I finally looked at the code and you were right, I was doing nothing wrong. Installing my blank component is what threw me off, because it only had modules positions and no component which made the page look different. I kind of like the breadcrumbs to span the whole page, but it looks good like it is now, so I won't complain.

All is well now and everything looks beautiful. Go WARP.

Problem solved.
