Want to delete achievements via the database and phpmyadmin

Even after I clear all of the users achievements, and reset their scores to 0, when I run a quiz w/ WPT-PRO-QUIZ I’ll get a “You completed your 1st quiz” achievement, and at the same time a, “You’ve completed your 12th quiz” achievement.

I imagine it has something to do with with the database not getting flushed when manually removing a user’s achievements in the wp back-end.

I believe I would have to do something with the below highlighted rows.
Could you assist me in flushing out the users’ achievement history?
