keyword problem

I spent about an hour creating keywords for Illinois.  I made a parent folder, USA, and then sublocations, such as Chicago, and then sublocations in it.  The Master Folder was Locations.  Then I noticed there was already a default Places folder.  I decided to move the USA, with all its subfolders to it.  I knew it would cause some problems and I'd have to do some re-checking in the new location and deleting in the old location, but now it has become an impossible situation.  If I check off one in under places and uncheck in Locations and delete that subplace, it also unchecks under USA, and if I check again, the sublocation comes back, and with all the parent folders.  Its like something that won't die.  They are like Elementary Particles, where affecting one affects the other. I changed an abbreviation in the subfolder to rename spelling it out and then I could delete the old one.  I thought I would do the same with IL, replacing with Illinois, but then I saw a sublocation appear under it, and I realized now I would have 2 ghosts, and quickly deleted that before doing anything more. I'd moved keywords before but never had a problem this extreme, but it seems one more bug in the update.
