Could you try again after uninstalling all plugins?
--------------------------------------------------------------------------------
please confirm the steps to uninstall plugins:

# run :rake redmine:plugins:migrate NAME=<PLUGIN_DIRECTORY_NAME_HERE> VERSION=0 RAILS_ENV=production;
# Delete plugin directory;
# restart redmine (Apache in my case);

Or do I need to stop redmine first?

I didn't know I needed to run that command to uninstall plugins, should add a message in plugins page about that.

I uninstalled others plugins I had just deleted the directory before (scrum and issues template) and also removed those three I had loaded.

The problem persists, once I set a transition I cannot unset it anymore.

--------------------------------------------------------------------------------
I have set "config.log_level = :debug".
There are no DELETE commands executed when updating the workflow.
By unchecking some transitions, it should run a SQL DELETE command, right?

(I'm using MSSQL 2017)

EDIT:
Looks like It should not execute DELETE everytime.
But there is something strange here.
The columns WORKFLOWS.assignee and WORKFLOWS.author are both set to ZERO, but it still rendered checked.

*Should it delete the WORKFLOWS records if both assignee and author are set to zero?
or least it should check the values when rendering the page?*

Because once I directly delete those records in the database, the checkboxes are no checked anymore.
