Lens is no longer recognized on NX30

Hi all!

I have a Samsung NX collection.
Among others, I have the 16mm, 30mm, and 45mm prime lenses.
Unfortunately, the 16mm lens is incorrectly recognized on the NX30, though it works fine on the NX300 and NX2000.
I have already downloaded the profiles several times, but without success.

Do we have a bug here?
