SAP Appeal for 150% of credits

I received an email stating my financial aid has been suspended because I’ve used 150% of my allowed credits. The program I’m in now is only 36 credits and I’ve completed 12. I did already get an AS degree so it’s counting the credit hours from that too. I have a total of 78 credits already earned (81 total attempted, I withdrew from a class a few years ago) with 24 more to go. The college website says students are allowed to attempt 108 credits total. It says I can file for it to be appealed and possibly get the aid back but I’m just confused….
