Azure Functions not showing up in Function app in portal

I've got a solution that contains a web app and class libraries. I added two Azure function projects to this, the first is version 1 and the second version 2. Both run fine locally. This code is in an online repository (Visual Studio Online, now Azure DevOps), and I set up continuous deployment from it to an Azure function set up in the portal. However, neither project is showing up under Functions in the portal although the code deployed successfully just like Azure websites and the URL says "Your Function App is up and running". I'm using Visual Studio 2017.
