I recently installed the IT service desk starter license as an add on to our Commercial Jira installation on our Server. I'm an admin for the main Jira installation and the IT service Desk, although I don't run the IT installation.
I'm not named as project or component lead on anything to do with the IT Service desk project, but when workflow transitions are made these appear to be automatically attributed to me (see below example from a typical ticket - I had nothing to do with the list of transactions shown!

The workflow for this specific task is the default "IT service request fulfilment workflow", which i've checked but couldn't see anything obvious in the transitions which would allocate this to me.
Very confusing!
