Any fixes to MLM 2 Pro yardages issues?

I just bought a MLM 2 Pro today and can’t seem to hit anything over 150 yards. My 7 iron that I hit around 150-155 can’t get over 130. And my 9 iron that goes 130 can barely get over 100. I’m hitting in my garage and even tried facing away from my garage door to no avail. Is this an issue with me or the device? Does anybody have any solutions? Thank you.
