Editing Subitem automation

Hi everybody, I’m a Monday.com newbie so still getting to grips with everything but already feeling the benefit! I have a quick query about editing an automation for sub-items: I need to add a couple more in but when i click on edit I just see the window below and cannot add/edit. Any suggestions to resolve? Thank you so much!

Duplicate the automation, make changes, save, delete original.
