The original problems are from _Digikam_root_tag_, which I added extra checks.

every occurrence of it will be deleted, so it doesn't matter if it is one
_Digikam_root_tag_ or 5 of them. 

The nested root tags I discovered in your metadata, some images contained:

_Digikam_root_tag_/_Digikam_root_tag_, probably old bugs...

The check I applied to both parts where digiKam read tags and where digiKam
write tags, clean-up can be done using any metadata writing option:

1. Write metadata
2. Maintenance tool
3. Tags Manager sync export options

Please note: if your tags database is empty and you trigger write, all metadata
from images will be cleared. Do not forget to read them before writing.

Also, about duplicate tags on the same level, digiKam do not allow me to make
them, even re-read do not reveal anything suspicious.

Only a corrupt database can contain this, use new one(when testing my fixes).

Also I tested the tag move to different sub-tree and it works, all tags are
correctly written and read.
