Let me explain again, and expand at the same time:
- I don't want the "piscine" at the root level, only as a hierarchical tag
- the tag piscine has 2 "legit" positions: in Sujets/technique/piscine 
and in Lieux|France|Charente Maritime|Le Mung|piscine.
- I did not create the tag "piscine" at root level. dK decided to create 
it by itself (but you have explained below how and why this happens).
- if I select "piscine 20200311_092408_vHDR_Auto.jpg " in the thumbnails 
view and uncheck the root piscine, dK recreates it as soon as I click on 
Apply. Again, I know now why, but I don't know how to fix it.

Hmm, BTW, I just copied those 2 paths above from "piscine 
20200311_092408_vHDR_Auto.jpg", and I notice the difference in 
separators. I guess this can't be good, but do you know any method to 
fix this? I guess that many photos are affected by this...

Well, the method may be easy, but I am unable to find it. Could you explain?

It is there. Search for "sange" and you will find it :-) Obviously a 
character encoding issue, but here again I don't know what to do about 
it. This could be inherited from the photo tagging software I used 
before, but I don't have it any more.

For several years now, dK has been my only way of editing tags. The only 
other graphical tools I use are Gimp and Hugin (and sometimes 
RawTherapee or darktable) and AFAIK none of those know what a tag is. I 
never used hierarchical tags before, hierarchical tags were one of the 
reasons I chose dK. Currently, dK is set to Xmp.digiKam.TagsList. Here 
are my tags settings:

Does Xmp.lr.hierarchicalSubject mean LR hierarchical tags? If so, IIUC, 
I should uncheck this, correct?

I guess this is the cause of the issue.

But how should I handle this? Should I ensure there aren't 2 different 
tags at different places? How can I clean my tags even assuming I am 
willing to replace Lieux|France|Charente Maritime|Le Mung|piscine with 
Lieux|France|Charente Maritime|Le Mung|piscine_dv?

Is there a tool showing which tags are "duplicated"?

Shouldn't this dK behaviour be enhanced in the future? Imagine a tag 
named "garden", there are bound to be many places in a hierarchy where 
such a tag would be appropriate. And one would not necessarily be 
willing to give a unique name to each "garden", because being able to 
pull all the "garden" from all over the hierarchy could be meaningful.
