**[Steps to reproduce]:** 1. Create a new delivery with a title of 80 characters and save it. 1. Click the clone button and do not edit the Public Name. 1. Click the Save button and observe the page. **[Expected result]:** * The clone is not created, and an error is displayed that the Public Name is too long. **[Actual result]:** * The clone is not created, but no error is displayed. **[Notes]:** * Cloning adds the " Copy" string at the end of the Public Name, making it longer than the 80 char limit. * A public name size error is displayed when creating a new delivery, but not when cloning one. * Attached a screen recording of the issue: ┆Issue is synchronized with this [Jira Bug](https://mozilla-hub.atlassian.net/browse/EXP-6011) ┆Attachments: <a href="https://mozilla-hub.atlassian.net/rest/api/2/attachment/content/98048">clone_clong_names_no_error.gif</a>
