Created attachment 147518 [details] the tree structure of the tags is puzzled I upgraded my hard disk to a higher volume version. After moving the pictures to the new disk I started a new database. I have checked the tags and the result is strange: the tree structure is puzzled (see attachment). The original tree is partially visible, a lot of "leaves" moved to the first rank, some virtual subsubsubsub branches are created with one leave - really strange. And it is not the first time. I changed the database several month ago and I got a similar result. Any hints? Correct the tag tree, delete the tags in the pictures and move the database tags to the pictures? Linux/KDE Plasma: ubuntu 20.04.4 LTS GNOME 3.36.8 X11
which kind of database type did you use exactly ? Gilles Caulier
If "Ubuntu Packages" is the Snap package? Numerous problems are now known. Snap packages use a sandbox and are unusable for use with digiKam. I understand correctly that they rebuilt the database from the image metadata? In order for this to work without problems, the digiKam tags metadata must be present in all images. Reading the digiKam tags must be the top priority in the advanced metadata settings. Otherwise, building up the tags tree is just a matter of luck, depending on which images the scanning process reads first. Maik

I didn't rebuilt the tags directly - I created a new database, added my picture folder and waited - slowly the thumbnails appear and the number of pictures in the collections incremented, then I checked the tags and was surprised. Xmp.digiKam.TagsList is the uppest line in advanced metadata settings.
A new database and add folders, scans all images and creates a new tag tree from the image metadata. And now the question arises, is the Xmp.digiKam.TagsList present in all images? If not, see what metadata in the images contain a full tag tree and set this to the top in the advanced metadata settings. You could have continued to use the "old" database. Maik

Unfortunatly I have to recover the backup. Markus
I have recovered the "old" database and the tags looks like expected. Do you recommend a special procedure to adjust the "old" database with the images on the new hard disk? Can you give some hints how to avoid such strange tagging in the future? E.g. delete all tags in the pictures and transfer the db tags to the pictures? (is it possible?) Or is the order in advanced metadata settings sufficient (it seems not to be) Best regards, Markus
It is important that at least one metadata entry contains the full tag path and that this is also set first in the advanced metadata settings. Our recommendation is the digiKam TagsList. To do this, the digiKam TagsList must be included in all images. Otherwise, the structure of the tags tree is a puzzle, depending on which images are rescanned first. Maik
