User has migrated from ArchiOffice to CORE, but noticed that the project names did not migrate properly and are displayed as numbers in CORE.
The project names have migrated to CORE, but you need to change the way the projects are displayed in your CORE company as per your preference. You can control how the projects are displayed in various screens and lists. In your case, it seems CORE is set to display only the Project ID. To change this, go to Settings > Projects > General and under Project Display As, select a format for the projects that includes the project name (for example, Project ID - Project Name). Check CORE Help Center for details.
