Again, that.grading system is not unusual and it will be explained on the school profile. FWIW our HS doesn’t give any GPA bump for honors, dual enrollment, or AP classes and students do very well in terms of college admissions (the class level can be determined by the course number on the transcript).
Admissions officers deal with all sorts of different grading scales (weighted, non-weighted, numerical, written evaluations instead of grades, various international grading systems etc.). It is part of their job. Some colleges go so far as to recalculate applicants GPAs using their own parameters (ex. core academic classes only). It is a non-issue.
Move on and focus on things that are in your control.
