We have seen an issue with the new Marketo UI where things appear to be created from the FO side (id, success msg) but items cannot be found in the Marketo tree or with the search.
Find the “FeedOtter Programs” folder in the customer’s Marketo account. Change the name to “FeedOtter Programs 123”, refresh the browser page. In most cases the programs will appear under the folder at this point. Continue with customer until everything is up and running.
