Lightroom Classic | CR2 vs CR3 RAW file | exported jpg file does not have same EXIF data mapping for "Lens" tag

Hi everyone

Just recently I bought the Canon EOS 90D which uses Canon's CR3 RAW format and I noticed a different behaviour for this CR3 RAW format vs Canon's CR2 RAW format in Lightroom in the jpg export functionality with EXIF data.

I took one picture with my other camera - a Canon EOS 77D (firmware 1.0.2, having CR2 RAW format) - with the Tokina AT-X 116 Pro DX II 11-16mm f/2.8 lens. (IMG_0008.CR2)
I took one picture with the Canon EOS 90D (firmware 1.1.1, having CR3 RAW format) - with the very same Tokina AT-X 116 Pro DX II 11-16mm f/2.8 lens. (IMG_0292.CR3)

Lightroom's data mapping for the exported RAW files do not match when comparing CR2 to CR3 regarding the Lens information. The values for "Lens" information of the exported jpg files are different from the original CR2 RAW to the CR3 RAW file.

As you can see below from the Exiftool data, in the RAW files the value for "Lens" tag is the same ("11.0 - 16.0 mm").
But as you can see for the CR2 file the exported jpg file has for tag "Lens" the value "Tokina AT-X 116 PRO DX II 11-16mm F2.8". While the jpg export of the CR3 file has for tag "Lens" the value "11.0-16.0 mm".
(You may also see that a few other tags have different values, e.g. Lens Info, Lens Model.)

This bothers me as I use/read certain EXIF data (like Camera model, Lens model, Focal length, Aperture etc) from the jpgs and output it to HTML code to display the tag/value next to the picture on my photography website and I would like to keep continuity and consistency in the data there.
After all, for both taken pictures I used (different cameras, 77D vs 90D but) the very same lens so I actually expect the same lens value there.

So far I only noticed this difference between CR2 and CR3 for that Tokina lens. Quickly checked my Canon EF-S 18-135mm IS STM lens and it outputs the same value for "Lens" tag in both RAW formats; CR2 and CR3.

It seems Lightroom's internal data mapping for outputting EXIF data to the jpg exported file is different from CR2 to CR3. Is this by design (what would be the justification for it being different) or is it a bug?

(I probably could apply a workaround in my code for outputting the tag/value in HTML by checking and replace a specific lens value with a hardcoded different value but I would rather have the issue rectified at the source than applying workarounds in my code.)

I did the following steps and am providing evidences:
- I copied both RAW image files (CR2 and CR3) into a new separate folder
- imported both files into the same (existing) LR catalogue at the same time
- took screenshots of LR showing the metadata in question
- applied for both images the same lens profile and correction
- exported both images with the same export settings at the same time
- ran Exiftool with option -*lens* -a -G1 on all image files (2 RAW, 2 exported jpg)
- exported Lightroom system information to text file

Please find the ZIP file (size approx 82 MB) with the evidences in a Dropbox folder.

Version 12.3, an update to Camera Raw, went live on June 15, 2020 and contains a fix for this issue. Please install the update and respond back if it does not cure the issue for you. Thank you for your patience!

Thank you for the information, Rikk. I tried it with the same steps as originally reported and the fix does work. 

And in an existing LR catalogue once I re-read the metadata for the picture from the file again the lens information also contains the updated value.

Thanks for the fix, guys!
