Editing pipeline steps does't work

Hello,
quick question I want to edit the pipeline steps for a project, but after editing the steps they keep changing back. In my case I want to change steps like Layout (Shortcode Lay) and Rig (Shortcode Rig) to lowercase layout and lay. It works on first view, but once you refresh or switch to a different page and back it changes back to the older step (first letter is uppercase). Even after deleting all pipeline steps & creating a new project this behaviour remains.
How do I change that in order to maintain step naming consistency with other steps?
