Quick band aid fix for ya!!!
Find a straight 2 footer and aim straight at the hole.
For 4 putts try to push the putt 1 inch right, 2 inches right, 3 inches right, 4 inches right
Reverse this for pulling the putt left as above. Always aim face straight and keep stance square as if you were trying to make the putt.
See which way is easier to DELIBERATELY miss whilst aiming straight
You should be able to miss either side just as easily in a neutral stroke.
After each set of pulls hit 4 putts straight at the hole and try to hole them at 4 different speeds.
After each set of pushes hit 4 putts straight at the hole and try to hole them at 4 different speeds.
Do this until you get to 64 putts. It does not matter how many you hole, just make sure you get closer to missing where you want to as time goes on.
This will reset your own 2 foot stroke without changing mechanics, I think of it as resetting your own internal compass. (Although I would seek a putting lesson to see if it is aim/path/read/rhythm that is causing your problems)
If you do all this for 21 days straight you will be putting like a legend from short range.
