The system is updating your "score" for those achievements. While you were gone your shop and stocks made enough for the achievement. I don't remember getting those messages specifically but these kinds of messages were not unusual when importing over to the new system.

If you feel that it truly is an error you can file a ticket or report it on this topic. Maybe you could check your shop sP total and see if it's similar to the value given?

Not a problem, glad I could help! Locking this up since your question was answered. Have a nice day!
