Is there anything we can do to help her at this point as far as the double charges for one crime?

My sister was arrested for shoplifting in north Florida where she lives. It was only one count of Felony Grand Theft when she was arrested about 3 months ago. Her boyfriend bonded her out on a $1000.00 bond. A week later, they got into a fight. He called the bondsman and revoked her bond. She went back to court and the charge was reduced to petty theft and she was able to bond herself out. She was out 6 weeks and then the bondsman revoked her bond today because she had not paid him the balance of the money she owed him on the bond and she goes back to court tomorrow. I guess he was afraid she was going to skip out on court. Anyways, when they picked her up, the paperwork the cop gave her boyfriend says they now have the 1 count for the 1 crime she committed but they are now charging her for a felony and a misdemeanor. Is this legal? How can they do that? My sister is a crack addict but the courts never have given her any help with a drug program. Instead, she went to prison twice and has not had a chance to treat her addiction this is why she steals to support her drug habit. I live 9 hours south of her and only her boyfriend is there to help her. Is there anything we could do to have the courts to help her? I am desperate. Please help and thanks for your kindness and time.
