You can instantly exterminate both of those .DS_Store files with this Terminal command:
rm -f ~/Library{,/Preferences}/.DS_Store
[i suspect however that Finder has some of that view info cached... especially if you have opened those windows since login. Therefore i recommend you relaunch Finder immediately after running that command. i could put a Terminal command for that as well... but it's easy enough to do via the menubar or the Dock.]
