I looked at it more carefully, and if this does load into RSD, it should be easy to fix. The header row has a 100% width, and it appears to have a subgrid of two columns. It appears that the subgrid is centered on the page, so that the color can go across the entire page.
It seems you want to things, the "header" and its tan row to be in line with the rest of the page, and the description tag to be closer to the logo.
Header row going across page
:n RSD, you should be able to apply a different background color to the row to get rid of that tan color. And in the subgrid, give it the tan color back (if not already applied). Do this to the Navigation also.
Tag line too far away from logo
The tag line on the right, is right justified, you can make that left justified, and that might solve you issue, because that will bring the left part of the text to a few pixels of the center of the page.
All of this can be in the Design Tab/Pane of RSD. Perhaps at some other breakpoint, you will be required to use the Layout tab/pane to adjust the subgrid of the header row.
Be aware, that if change the colors that go all the way across, you may want to change background images. The row with the big image, is also a row that is 100% wide, with a centered subgrid, and has a background image that subtly adds some vertical texture to the background. You may want to get rid of this entirely, or remove it and add that to the grid itself so it is at the top. The background image is here (and repeats in x), because the top two row colors extend across the entire page in the original template. Remember that these subgrids do not appear like a subgrid you would initially add with RSD. These subgrids are just one row with two columns in this page. The use of subgrids may appear elsewhere in the template, and may have different compositions of rows and columns. Depending on your skill level, this template can be recreated entirely without subgrids, but that might be for a different day.
Read this about spans. Subgrids are a set of spans, within the main subgrid.
