Adobe Analytics Data Feed "Saving feed failed"

Hello everyone,

I recently configured an SFTP data feed and executed two exports. However, despite the data feeds being marked as complete, my SFTP location has not received any files.

Previously, I tested the SFTP location (for a different report suite) and confirmed that it was receiving the export files.

Now, when attempting to create a third data feed export, I encountered an error message stating 'Saving Feed Failed' (screenshot attached).

In summary, I have two questions:

1. Why am I unable to see any files in my SFTP location despite the data feed being marked as 'Complete'?
2. Why am I unable to save a new data feed (attached screenshot)?

Any insights or assistance would be greatly appreciated.

Thank you!
