Attendance History and Days Enrolled on the Attendance page are not matching. AHS Update uses legacy logic that only processes tracks A–F. When tracks beyond F are encountered (e.g., Q), the track value is zeroed and AHS falls back to generic holidays (HO) instead of the track‑specific holiday column (e.g., T17 for Track Q). Result: Days that should be excluded for Track Q aren’t excluded in AHS, inflating “Days Enrolled.”
