My Spark projects are gone

All of the following projects were created in Spark in 2016. https://express.adobe.com/page/YpBbk/ https://express.adobe.com/page/0kzb1enO2ETNg/ https://express.adobe.com/page/NNhvPv5Q9vaiy/ https://express.adobe.com/page/hPXmcxIUO6wYh/ The urls have been changed to Adobe Express URLs, yet they do not appear in Adobe Express when I log into my adobe account. How can I access my content and edit the projects?? I tried logging in via my other adobe account to no avail. They aren't there either. I tried logging in various ways i.e. through gmail, email, Facebook, etc. Still no luck.
