So confused ! Smear different to biopsy . . Help!

Smear showed HPV and abnormal cells. Had Colposcopy 6 weeks ago and the colposcopiet said it looked a bit worse than what the smear had shown.
Now the biopsy results are saying no HPV and I just need a smear in 12 months.
Firstly, why haven’t they mentioned anything about the abnormal cells . . And the colposcopistntold me that they would treats even CIN 1 with LLETZ as I’m over 40 . . Confused !!
