Incomplete EXIF with Nikon Z7

Hi, in addition to the manufacturer's lenses I also use some Sigma and Zeiss glass on my Nikons. When I import photos taken with the D800 into Lightroom Classic, it shows for instance that the lens used was the Zeiss Distagon ZF.2 35/1.4.

When I use the same lenses on my Z7, Lightroom will only report "35.0 mm f/1.4", so there is no way of distinguishing between, say, the Sigma 35/1.4 and the Zeiss 35/1.4.

Interestingly enough, when I import the same files into DxO PhotoLab 2, I get the correct lens info, so it must be embedded in the EXIF.

Is that a known problem? Anything I might be doing wrong during import?
