Have you been pulling or pushing a lot of short putts lately? If so, you might want to check the first part of your backswing.
A lot of short misses happen when the hands are the first thing to move on the backswing instead of the putter-head.
I don’t like missing short putts so I make sure to swing the putter-head smoothly away from the ball a split second before my hands go back. I’ve always felt like it’s my left shoulder rocking back which starts the putter head in motion before my hands. This feeling gives me balance and rhythm in my stroke which leads to more makes from close range.
