Hello @GillianG63 ,
Are you using the official Constant Contact Forms plugin for Wordpress, or are you using something developed by another source? There shouldn't be anything on our end that would be preventing a list from being available as all lists in an account function the same way. If it was a list that was just created, its possible that the integration hadn't had a chance to resync, and just needed overnight or a full 24hrs to refresh its cache.
If you are using the plugin, I'd recommend calling our general support and requesting a transfer to the Tier 2 integrations team for live troubleshooting. If it's something you developed using our API, then I'd advise reaching out to our Web Services team here in the Community or via their main site. If it's a 3rd party developed integration you're utilizing to connect your WP site to your CTCT account, then it may be worth reaching out to those devs.
