The third problem I found is when you create an event and do some steps will show the name of the last step. For example if the first step is the details and the last is personalization, the name of each step will be displayed as Personalization tab in the browser.
Is it possible for you provide us some screenshot regarding this so I can better understand which area having this issue?
