I don't think this game is for me but still congrats on building something!

A quick side note: I kept getting notifications for unlocked achievements that I certainly did not fulfill the requirements for, e.g. "Play a whole season" after the second tournament or "Earn a million" after I had made maybe 50k.

It takes into account your whole golfer profile so if you choose an Elite player then the game will check against his lifetime earnings and other things. I'll try to fix that or enable an option to start fresh so that you aren't inheriting a golfer already but I believe that's intentional design so far.
