Finder drag and drop file issue (snap to grid)
I'm having issues with my Finder in that when moving files to another folder by dragging the file and dropping it onto a directory in the sidebar, it doesn't move the newly moved file to the very end of the folder. Here's a few screenshots showing the issue: 

As you can see in the last image, the file sig.html is right on top of a folder. Also, just to be clear, the Documents folder has more than 10 things in it and this file happen to be moved to 4th row, 1st column (I set my folders to only have 5 columns).
This does not happen in the root folder and a few other places. I've tried Automator to set view options, I've manually deleted .DS_Stores, finder.plist, and resetting the view options and then clicked 'Use as Defaults', but none fixed this issue.
Not sure if it's relevant or not, but I upgraded from Mavericks straight to Sierra.
I'd appreciate any help to fix this.
