As I don't use digikams sidecar files I can only guess: Have you enabled
sidecar files in digikams config dialogue (in the metadata section at
the bottom of the list)?

I don't know of any. I usually use darktable for raw development and
export to jpeg/png. After this I tag my photos with digikam. If I have
to rework my raw settings I do it and let darktable export the photo (it
gets the original file name with "_01" as postfix). After that I extract
the exif data from the old photo, delete the old one, remove the "_01"
postfix of the new filename and import the exif data back (now to the
new file). With this I don't loose any settings. But I have to tag all
photos twice (mostly done in one run anyway).
