If you are seeing this error, here are the steps to resolve.
Important: This is from lab 3.5. You will need to delete all 8 business services to resolve this issue. Even if the error is showing 6.

Step 1. Delete the CIs
Click on 'Additional Info' then select 'List CIs'.

Then select all of the CIs and delete them.

Step 2. Delete the Endpoint
Click on the minus sign next to the endpoint to remove it, then confirm by selecting 'Remove'. Then press 'Update' on the business service to update the service to reflect the removed end point.

Step 3. Delete the Business Service
Click on 'Delete Service' to remove the business service.

Step 4. Re-run Discovery (Candidate)
Repeat steps 2 and 3 for all of the services that need to be fixed. Once the Service Maps show all of the multi error services moved from Fix (now greyed out) to Map, then click on Map and Continue (to map all business services again).
You may need to delete the remaining 2 manually from the 'Business Services' menu option. So the screenshot below is likely to show 8 in most cases.
Important: Wait for ALL business services to complete mapping before continuing to further labs.
