Armoury Crate not finding driver updates

[gigno]

Hi everybody, i'm new to this forum
I googled about my trouble but i found nothig about it...

My Armoury Crate app is not finding any driver update at all
First i thought that there wasn't any update, but searching manually on the support page of my mobo (Z390-E) i found many driver updates.....

So have any of you noticed this curious thing on his rig?
That's a screenshot about my situation, with current version and last version of my drivers.
