Hi,  
Not sure what you mean by “how to proceed” here. These states are normal information on what the threads have done or are doing at the moment. 1. tells you the applier thread has done some TOI query in the past (DDL) and it’s number. But it’s idle at the moment. 2. Aborter thread is also idle at the moment (it gets fired only for resolving conflicts). 3. Some local transaction is in the replication/certification phase.  
Some additional information:
