Boolean configuration settings not editable in tools - advanced - expert configuration

I noticed a general unexpected behaviour when working with LibreOffice in Tools-Advanced-Expert Configuration.
When the setting is of type boolean, I cannot change the setting. I tried various existing settings, mainly in org.openoffice.Office.Calc and both with current Master and version as distributed with openSUSE Leap 15.0.
My conclusion was that for reasons unknown to me, boolean settings are not editable and int settings are.
So I choose to use an int as type for a setting that is 'on' or 'off'.
I forgot to mention this behaviour in the mailing list when I made my discovery.

I'm trying to put that right now, and I would like to know whether the behaviour I described is intentional, a bug, or whether I did something in an incorrect way.

I hope this clarifies the situation.

WRT the specific issue, I want the setting to be of type boolean _and_ I need the setting to be editable. The latter is the most important at the moment, as the exact location (registry and/or document) and the accompanying UI are yet to be decided/inplemented.
