The problem is the profiles--most Addons (I say most) use a profile save method where they attribute a setting to a character. Simply copying your character folder and renaming it to your alt does not help.
The only recommendation I can tell you is to see if Reflux is included; or go into each addon manually and make sure in the "Profiles" option; they are the same choice that your main has.
I don't know how that UI you use it setup; but I can tell you for my UI, every addon that can save a profile is named "CalaiUI" so that it's easy for folks to setup their alts.
