So the issue isn't really the geocoder, although it's something that might be nice if the geocoder did handle better.
Your address: "2619 NW 55TH BLVD,GAINESVILLE,FL," has an extra comma at the end. It does indeed give the wrong address and lat/lng, which is kind of weird. If you try the address without the extra comma like this: "2619 NW 55TH BLVD,GAINESVILLE,FL" you get back the expected output:
"2619 NW 55TH BLVD,GAINESVILLE,FL" - 2619 NW 55 Blvd, Gainesville, FL, United States at 29.705313,-82.36112
