help needed fans not showing up in bios z-390 f

[zayah]

I have asus rog strix z-390 f gaming that i got 2 years ago and for the first time decided to update bios and after that i noticed i cant see my fans in bios. I have aio and those fans show up in bios in cpu as i hve the fans connected liek that and the fans at the top are all connected as well as cha. 2 fans but my rear fan which was cha.1 fan does not show up in bios, and it did before i updated bios. i made sure to check pwm is checked like it was before, but for some reason i cant see it in bios or monitor it w hwmonitor anymore after the update. i used ai suite 3 for it and ezflash. could there be some setting i have enable in bios, since the bios update reset all the bios settings? im so confused
