After post-processing and exporting from Lightroom Classic, I find out Lens ID of JPG file is not same with RAW file. But I do not edit exif info in Lightroom.

Exiftool version is 13.55, and I also reproduce the issue on the lastest version 13.57.

Adobe Lightroom Classic is 15.3 and Adobe Camera RAW is 18.3. They are up-to-date both.

Reproduction steps

1. Take the picture with Canon EOS R7 and RF 200-800mm F6.3-9 IS USM
2. Import the RAW file from camera to Adobe Lightroom Classic on Mac.
3. Export the JPG file the after post-processing. Notice: There is no operation to edit metadata when post-processing.
4. Run exiftool command to show metadata — LensID shows as Canon RF 100-400mm F5.6-8 IS USM + RF2x
