losing metadata after running Darktable edits through Lightroom

Hello
I use Darktable on Linux to make basic edits on my DNG files, export as JPG and then run the JPGs through Lightroom (cloud version) to improve the exposure and "pop" .

However, when I save/download the final JPGs from LR, I lose metadata. I need the "Derived from" info to remain intact so that I can find the original DNG file on my hard drives. The files I get out of LR say Derived from: type="Struct".

Is there any way I can avoid this and retain the original DNG filename in this field?

Thanks a lot!
