Left column/widget left justified - large gap between widget and center column

Hi, the other post was getting very cluttered so I thought I would start a new one to avoid confusion.

I am having 2 issues:
1) my left column is forced all the way left, leaving a large gap between it and the center column. I uploaded a new copy of the theme, which worked yesterday when I had the same issue but it didn't work this time.

2) files in my child directory are not being read/used. I have created the proper directory structure and checked permissions and all is fine. Copy the file into the replica child directory, remove changes from the main theme file and it no longer works. Change the main theme file back and it works.

Any help would be appreciated.
