Indoor distances off….

Since the update, my device is now registering about every shot. But my indoor distances are way off, I’ve got 10ft of ball flight and the garmin is 6-8 ft behind my hitting area at the same level. I’m usually 25-35 yards short off my averages and sometimes upwards of 50.. I tested it outdoors at the range and it worked extremely well, I would say with-in 5-10 yards max  and the numbers were what I would expect. Has anyone found an effective way to combat this as it doesn’t allow me to adjust the settings of carry etc.   I’ve noticed that clubhead speed and ball speed don’t correctly correlate as a lot of times they will be with 1-3 mph of each other..   I was hoping to use this mainly indoor through the winter.. any help is appreciated
