How can I erase a process step from a category?

In order to no longer assign one or more process steps to a category, click on System under Settings.

Then you have to click on categories and processes.

In the overview, by clicking on the category, the category can be selected to which a process step is to be assigned.

Click on the category to select it.

The process step that should no longer be assigned must be selected.

The process step that is no longer assigned is then found again among the available process steps.
