MM, not sure that I understand your comment. Your stats say that you took a 'break" from WGT play (for some time in excess of 6 months?) and started playing again in September. Your scores at Bethpage and Kiawah from mid-September (2014) look quite reasonable for someone who has been away for a while. You stopped playing ranked rounds, again, until yesterday. When you returned, you played Blitz, but not on courses with "reasonable" - i.e. fairly flat - greens.
If you want to improve your putting, start with courses offering "friendly" greens (Kiawah and St. Andrews immediately come to mind). Try practice rounds so that you can use the 'mulligan' feature to correct your errors.
FWIW, the Nike ball that you are using is pretty costly and the 'mulligan' feature cuts your ball life in half (i.e. 1 stroke on a mulligan=2normal strokes). This Forum indicates that there doesn't seem to be a big difference between ball performance on the putting green - so the cheaper the ball - the better (when learning to putt).
Good luck.
