Florida bar membership is something that can be determined from public records to see if he is an attorney or not. I would be stunned if he was not.
It could be that he was an enrolled patent agent prior to being admitted to the practice of law and has never updated the record. Alternatively, it could simply be that there was a data entry error. No large database is 100% accurate.
For most purposes, the rights of an enrolled patent agent and an attorney admitted to patent law practice are the same in PTO practice, so correcting this error (assuming that it is one), even if it was discovered, wouldn't be an urgent priority.
