Have you tried running the command on the MDM to swap between primary and secondary?  I was wondering if your just having a display issue and by issuing the command it might correct that.  Page 324 of the user guide.

scli --switch_mdm_ownership (--new_master_mdm_id <ID> |

--new_master_mdm_ip <IP> [--new_master_mdm_port

<PORT>]| --new_master_mdm_name <NAME>)

Can you please post the output of "scli --query_cluster" here. You may mask the IP addresses in the output before posting them here.

You may try to restart the MDM service on both the MDMs one by one.

Stop service:

/opt/emc/scaleio/mdm/bin/delete_service.sh

Start service:

/opt/emc/scaleio/mdm/bin/create_service.sh

Thereafter again check the output of "scli --query_cluster"

Since both MDM's are in secondary state you can't issue scli commands

Can't use the command since both are secondary

This is the error I get after service restart :

scli --query_cluster --use_nonsecure_communication

Error: MDM failed command.  Status: The command used for Tie-Breaker is not allowed

I guess now all the three are showing as Tie Breaker

Is the the same error when you run "scli --query_cluster" on all the 3 MDMs?

I will suggest to collect get-info from all the MDMs and open a Service Request with Tech Support and we can investigate.
