Sensitivity option is unavailable in Excel 365 proplus

I have Office 365 E5 and enterprise mobility + security E5 subscriptions,

I have Office 365 proplus (enrolled into insider) installed on my Windows 10 insider fast ring,

I have configured the sensitivity settings here, created label that includes all of my organization and also published it for all users

still when i go to Excel 365, the sensitivity option is unavailable. the same happens in Word.

I already checked out this article:
