That may be because you logged back into your Google account, it saves your settings in your user profile.
You can try uninstalling it, then manually going in Program Files, deleting any Chrome directory there, then going into your profile in the AppData\Google\Chrome directory and deleting that. You should make a copy of it somewhere before deleting it just in case something works funny afterwards. Then install it again and see how it works.
Aside from that, you may want to try creating a new user profile in Windows and check on that, at times files and registry keys get corrupt and don't save things they way it should.
