I created a simple home page template for LEX.  When I use it though, I see all these extra fields vertically displayed.  I'm trying to hide all of these showing up- I want just the handful that show up with the default home page template.  Can someone please point me in the right direction on how to get it working?

I have very little development experience, but need a simple template that is one row across on the top and then 2 columns below- shocked it's not an available one by default.
