I can not reproduce the problem. Can you please test it with a more recent version (AppImage) from here?

I cannot reproduce here too with current 5.8.0.

Did you use a specific metadata settings in digiKam or an older Exiv2 library version ?

"Read from sidecar files" set, "write to sidecar files" set with the menu set to "Write to image and XMP sidecar".

$ ldd `which digikam` | grep exiv
        libexiv2.so.14 => /usr/lib/x86_64-linux-gnu/libexiv2.so.14 (0x00007f3ec8c90000)

Note : digiKam 5.8.0 pre version bundles are just updated to https://files.kde.org/digikam/

I just downloaded the 5.8.0 appimage (64-bit) and ran the same workflow as before. The results are the almost the same - a number of .xmp files which should not be there any more. The directory "Watermarked" was created on 5.7.0 and "Watermarked2" on the 5.8.0 appimage.

The workflow is the following tools in Batch Queue Manager;
1) Apply Metadata Template
2) Convert To JPEG
3) Add Watermark

I can confirm it, the cause is a combination of writing the metadata in file and sidecar and convert to a new image format.
