On Office 365 home page, where are the custom apps under "All apps" coming from?

Hi,

On the Office 365 homepage, you can see 3 links: Office 365, All apps, and Tips and Tricks. 

Under "All apps" we are seeing custom apps that often when clicked result in a 404 or a failed sign on. We have one application we use for workforce management and people are seeing multiple instances of this app showing up under all apps, and the links do not work. When we look at the URLs underneath any of these custom apps (all with light blue icons) they all start as so: https://account.activedirectory.windowsazure.com/applications/ 
Is there a list somewhere in Azure that we can delete these apps\icons out of and prevent any new ones from being created?

Those are "Azure AD integrated" apps, you can manage them under the Azure AD blade > Enterprise apps: https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/view-applications-portal

Awesome and thank you!
