I'm not sure what the purpose of your question is. Are you wondering whether that citation should have been issued to your California DL instead of your FL DL? And if that is the case, what difference does it really make? You say it is a non-moving violation so the assumption can be made that it will not affect your driving record either way.
Alternatively, are you wondering whether you can be found in violation for having two driver's licenses at the same time? If that is the case then as long as your FL DL remains to be "punched" then you should be OK. Here is the CA statute regarding "more than one DL"...
California Vehicle Code Section 12511. No person shall have in his or her possession or otherwise under his or her control more than one driver's license.I would venture a guess that FL's statute has a similar restriction in that it prohibits "possessing" more than one DL.
Let me just add that if you have "moved" back to FL and are no longer residing in CA, you should change you vehicle registration as well as your DL back to FL... a simple "change of address" with the CA DMV will not suffice.
