Hello Forum

I am missing all tags after synchronizing images exported from LR.

admin/tools/synchronize/Synchronize metadata shows::
> Synchronize metadata (filesize, width, height, date_creation, latitude, longitude)

There are no tags in the metadata list and no tags are imported after synchronization.
Most importantly, also keywords are missing that should be imported as tags.

I have a second installation where the problem does not occur:

were the tags are imported from keywords:
admin/tools/synchronize/Synchronize metadata shows:
> Synchronize metadata (filesize, width, height, date_creation, latitude, longitude, keywords, author, name, comment)

Here additional fields  (keywords, author, name, comment) appear and keywords are imported as tags.


Can anyone exlain this?
Where/how are the metadata-fields defined that are import during normal syncronization?
