[SOLVED] Kanban settings are not saved between sessions

Creating a new post because the first one contained too many issues and wasn't receiving any more answers.

The settings in the top right of the kanban view are not getting saved. When I disable "show work on elements" it becomes enabled again once I log out and back in.
As stated in the previous post, an analysis on the database shows that the setting is written to the database, but seems to be ignored on loading.

I looked into the database to find where the parameters for kanban are stored, specifically the 'show work on elements'.
For my user it is stored in parameter with parametercode kanbanSeeWork8 and value null.
When I log in the checkbox is enabled and work is shown on all elements.
Changing the value of the checkbox correctly writes null or 1 into the database and updates the display, but it doesn't read the value on login.

The demo correctly saves the settings.
I think the issue might be related to the database, because we are using postgresql instead of mysql.
I can send you a dump of the parameters table if that helps with analysis.

I successfully reset my settings with the mentioned command. The setting is still not saved after configuring it again.
I have noticed that the setting "show large elements" does save correctly, but it uses 'on', 'off' instead of null, 1. I have manually set "kanbanSeeWork8" to 'off' and it now loads without a problem.
The issue returns when I change the checkbox, then it writes 1 and null again.
