That looks like it's coming from the '_best_semester_trimester_annual_percentage_' custom field, not the best_academic_gpa taxonomy.
It does not seem to be visible on the post editor screen, but that custom field exists for sure. Also, if you check, the academic performance taxonomy terms are not checked within the post editor on that post: https://i.imgur.com/Dk00hCi.png
Those taxonomy terms are definitely empty, and that other information comes from custom fields, I guess.Best,
