Fuji X100F lens unknown in Lightroom Classic

[HH-]

In filters > metadata, I added Lens column, and it recognised 12 different lenses I used, even the iPhone, except the Fuji X100F lens, which sits in the Unknown group.

1) Why?

2) How to solve it?

3) Is there a way to assign lens metadata to the old photos in Lightroom?

Thank you.

The X100F uses an embedded lens profile.
