Aliases not registering

Really liking Corelcad as an alternative to autocad so far.  Very comparable and great for the price!

I have a habit of changing the aliases for Circle to CI and Copy to C.  Easy enough..

I've changed the settings in the options/user prefs/aliases but the old C =Circle, CO = copy are still hanging on.  I didn't add the new items.. I changed the existing settings.  When I go back into the prefs, my options are there but no luck on them working.  What am I missing?
