Edgard,

The "F" key as in my example does not have to be there in your case. Database Explorer stores its values in a MRU list based keys and what was "f" might be "a" after deleting the old branch. Important is that I don't see a "container" key in your screenshot so the fix I made in July 2020 does not apply here. And you are running the same version as I.

So we need to find a situation where the missing area occurs and then fix that. Without reproducable steps I won't know where to look and what to try to fix. I hope you can give more clues, have an exact situation, create steps.
