yesterday I built a workflow and published the workflow. Today I wanted to change a workflow action but when I tried to save or publish the workflow the system does not react. It seems like the workflow got saved/published but after some seconds the 'save window' (picture below) appears again. The changes do not get saved. This reaction always appears by pushing the 'send'-button.
I noticed that the checkbox 'overwrite available version' below the title field is missing. Example from another workflow:
This reaction only appears by saving/publishing this workflow. Saving/Publishing other Workflows do not have any problems.
