I have a client who is on CRM 2015 on-premise and it errors out when trying to export it and there is no log file to download. After troubleshooting I notice that when I click on client extensions I only see the site map and the Application Ribbon is missing in the default solution. Since it is missing from the default solution I am unable to imported updated managed solutions that are currently installed in the CRM instances. In the import log file there is no error it only shows items where processed until it gets to the sitemap it errors and shows unprocessed.

I tried creating unmanaged solution and add all the components and when under client extensions click add existing and select the Application Ribbon the following error occurs:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: There should be exactly one ribbon customization in the active solution.Detail:

It looks like the application ribbon is corrupt. How can I get the application ribbon to display again in the default solution and only have one application?
Additionally, I did turn on CRM trace and there is no other errors other then these.
