When you go to "schedule file export" from the share menu within a project, it will give you the option to set up a new export, it won't show you the current export or the list it is being sent to.
If you want to see the list it is being sent to, you need to go to "scheduled projects" under the components menu.
From that landing page, it will have all of your current scheduled projects. Click on the name of the one that you want, and it will open up the editor. This will have all of the populated fields, such as when the report is being sent and who it is being sent to. There you will be able to see everyone on the recipient list, and if needed, you can update the list there too.
