Digikam 7.2.0 AppImage: Lens information missing in DNG from Canon R6 which was there in previous images

Hi
I converted some files from CR3 to DNG in digikam.
When I tried to do Lens correction in Darktable, there was no lens information.
I checked DNG file properties in Digikam and there is no Lens information

Mode/Program and White balance metadata is also missing .

I didn’t change any default setting except checking Embed raw file.

How should I start troubleshooting?

Thanks
