You have several pictures with keywords: indoors, garden, fountain, pool, etc.
Drag and drop the other keywords into "kplaces"
I have installed the operating system from scratch.
Due to the Lightroom errors, I have reinstalled 3 times.
The only extra action that I have made is to create app keyboard shortcuts in the System Preferences of the operating system, to sort by rating, aspect ratio, etc.
As far as you know, we provide our software as is, without warranty of any kind.
According to our policy, the screenshot that you have sent to us is totally discredited because our quality control team can not reproduce the error that you inform us, therefore, you don’t have any problem.
The status of your post will be changed to “Not a problem” and no further follow-up will be provided.
I haven't run across anyone else having this/these particular issues and I am thinking you have a system specific problem.
1. A hosed preference file.
2. Something wrong with the specific catalog.
Create a blank catalog and attempt to perform the keyword operations. Do they work in the blank catalog? If so you may need to repair/have repaired your catalog file.
If not, then you need to provide some information. Mac OS Version? Actual installed Lightroom version number? Much more information about your catalog?
