Hi,
I just extended the classic workflow for Jira tasks for two additional status and some additional transitions. See picture below:

However, for older tasks some of the transitions do not appear in the menu, although the tasks are totally the same exept for the date they were created. See next two pictures.
Without additional transitions: 
With additional transitions: 
Note: Both tasks are the same in the same projekt except that one task was created before the change of the workflow.
Do we need to perform any kind of refresh to get to see all possible transitions within older tasks, that were created before the extention of the workflow?
Thank you for your answers.
